Description Christopher Beland 2007-02-20 17:59:09 UTC
I have many programs running on my desktop...I remember starting xmms playing, and suddendly I got this message from the kernel: Oops: 0000 [#1] SMP CPU: 0 EIP: 0060:[<c0486d16>] Tainted: P VLI EFLAGS: 00010206 (2.6.19-1.2911.fc6 #1) EIP is at clear_inode+0xe0/0x16b eax: 00004005 ebx: c0007b04 ecx: c0323d9c edx: ede86000 esi: c0007c90 edi: 0000002b ebp: ede86efc esp: ede86ed0 ds: 007b es: 007b ss: 0068 Process kswapd0 (pid: 167, ti=ede86000 task=ede0b250 task.ti=ede86000) Stack: c04867fc c0323f28 c0007b04 c0007b0c c0487041 e5193b84 00000000 00000080 00000080 c048723f 00000080 d551f874 ea17fce4 0000170c ededa440 00000086 000000d0 c04604be c045db8a c069b000 0000577f 00170c00 00000000 00170c00 Call Trace: [<c0487041>] dispose_list+0x36/0xb7 [<c048723f>] shrink_icache_memory+0x17d/0x1a5 [<c04604be>] shrink_slab+0xd9/0x142 [<c0460864>] kswapd+0x2c1/0x3ac [<c0439878>] kthread+0xc0/0xec [<c0404c03>] kernel_thread_helper+0x7/0x10 ======================= Code: b9 90 63 48 c0 ba 03 00 00 00 89 f0 c7 04 24 02 00 00 00 e8 08 de 19 00 f6 83 94 01 00 00 20 75 2e 8b 83 c0 00 00 00 85 c0 74 24 <8b> 40 24 85 c0 74 1d 8b 50 04 85 d2 74 16 83 bb 44 01 00 00 00 EIP: [<c0486d16>] clear_inode+0xe0/0x16b SS:ESP 0068:ede86ed0 This is with kernel-2.6.19-1.2911.fc6. This only happened once. xmms stoped responding to clicks, and even a kill -9 did not clear the window. I rebooted my system and ran fsck. No filesystem errors were detected. Upon reboot, everything seems to be operating normally, at least for the last few hours. I have not experienced any kernel oopses in many years, but have had several in the past few weeks. One kernel-related thing that I did do at about the same time this started happening was to fix my wireless router. I had my wireless card configured with Fedora 4, and when I fixed my router, I set up the wireless card for the first time with Fedora 6. In order to do this, I unload the bc43xx module (which complains about missing microcode), load ndiswrapper, and configure the wireless card using Windows drivers. I did not have any kernel problems with Fedora 4 using ndiswrapper, but now I am wondering if my recent oopses are related to the wireless modules. (Though this seems odd since all the oopses seem filesystem-related.) Currently I have installed: kmod-ndiswrapper-1.25-22.214.171.124_1.2911.fc6 ndiswrapper-1.25-1.lvn6
Comment 1 Chuck Ebbert 2007-02-27 21:48:04 UTC
ndiswrapper can cause problems like this. What is the problem with using the native bcm43xx driver?
Comment 2 Christopher Beland 2007-03-03 04:33:17 UTC
Hmm, I have also begun to experience not infrequent failures to wake up (the system wedges hard) after suspend, which seems to be correlated with ndiswrapper use. There aren't any log messages produced when this happens, as far as I can tell. The reason I'm using ndiswrapper and not the native bcm43xx driver is that the latter requires some sort of firmware upgrade before it will work. (See Bug 183273.) That sounds scary and not necessarily easily reversible. The ndiswrapper method was working fine for me under Fedora 4, without these adverse symptoms, so I decided not to risk changing things.
Comment 3 Christopher Beland 2007-09-05 00:00:04 UTC
Well, for anyone else using ndiswrapper who wants to switch to the native bcm43xx driver, I managed to successfully do so with the following procedure: * yum -y install bcm43xx-fwcutter * From: http://linuxwireless.org/en/users/Drivers/b43#devicefirmware Download and untar: http://downloads.openwrt.org/sources/broadcom-wl-126.96.36.199.tar.bz2 * Remove any old bcm43xx_* files from /lib/firmware * According to README.fedora in bcm43xx-fwcutter RPM: cd broadcom-wl-188.8.131.52 bcm43xx-fwcutter -w /lib/firmware kmod/wl_apsta.o * Reboot * Use NetworkManager (on desktop by default), choose network I do still occasionally experience kernel oopses, but I'm not sure they're related, so I report them under separate bugs.
Comment 4 Jon Stanley 2008-01-08 01:49:36 UTC
(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Comment 5 Christopher Beland 2008-01-23 22:01:37 UTC
This might be the same as bug 291329, which I experienced without the evil influence of a wireless card.
Comment 6 Christopher Beland 2008-01-23 22:10:59 UTC
Sorry, I mean bug 428329. I suspect there might be a general problem when I suspend/hibernate which results in a variety of kernel crashes.
Comment 7 Bug Zapper 2008-04-04 06:19:02 UTC
Fedora apologizes that these issues have not been resolved yet. We're sorry it's taken so long for your bug to be properly triaged and acted on. We appreciate the time you took to report this issue and want to make sure no important bugs slip through the cracks. If you're currently running a version of Fedora Core between 1 and 6, please note that Fedora no longer maintains these releases. We strongly encourage you to upgrade to a current Fedora release. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained and closing them. http://fedoraproject.org/wiki/LifeCycle/EOL If this bug is still open against Fedora Core 1 through 6, thirty days from now, it will be closed 'WONTFIX'. If you can reporduce this bug in the latest Fedora version, please change to the respective version. If you are unable to do this, please add a comment to this bug requesting the change. Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we are following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again. And if you'd like to join the bug triage team to help make things better, check out http://fedoraproject.org/wiki/BugZappers
Comment 8 Bug Zapper 2008-05-06 19:16:00 UTC
This bug is open for a Fedora version that is no longer maintained and will not be fixed by Fedora. Therefore we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen thus bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
