Description Chris Ricker 2003-01-12 19:30:33 UTC
I'm currently on a fully up2date RHL 8.0 system w/ 2 PII CPUs running the
kernel-smp-2.4.18-19.8.0 kernel.

Sometimes, after periods of inactivity, my USB keyboard will be "hung". The LEDs
will blink, and the keyboard will not respond to any key presses. Unplugging and
replugging the keyboard in resets it and makes it responsive again.

Messages displayed while the keyboard is hung:

Jan 12 12:15:20 verdande kernel: usb-uhci.c: interrupt, status 3, frame# 920
Jan 12 12:15:25 verdande kernel: usb-uhci.c: interrupt, status 3, frame# 1864
Jan 12 12:15:30 verdande kernel: usb-uhci.c: interrupt, status 3, frame# 760
Jan 12 12:15:35 verdande kernel: usb-uhci.c: interrupt, status 3, frame# 1704

every 5 seconds

then unplug and replug:

Jan 12 12:15:39 verdande kernel: usb.c: USB disconnect on device 3
Jan 12 12:15:40 verdande kernel: hub.c: USB new device connect on bus1/2, assign
ed device number 4

board and Mouse] on usb1:4.0
Jan 12 12:15:40 verdande kernel: input1: USB HID v1.00 Mouse [QTRONIX USB Keyboa
rd and Mouse] on usb1:4.1
Jan 12 12:15:44 verdande /etc/hotplug/usb.agent: Setup hid for USB product 5c7/2
Jan 12 12:15:44 verdande /etc/hotplug/usb.agent: Setup keybdev mousedev for USB 
product 5c7/2011/110

and it works again, at least until it hangs again.

This isn't specific to this 19.8 kernel -- I saw it with older 8.0 kernels as well.

It only seems to occur when the keyboard is idle for a while and only while in X
(but I tend to always be in X on that system, so that may or may not be
required; similarly, I presume its a kernel problem, but it might be an X
problem since I've only seen it there)

usbview describes the keyboard as:

I'm using the usb-uhci controller module. This system's USB controller is:

Comment 1 Chris Ricker 2003-01-12 19:46:32 UTC
BTW, if it matters, this keyboard has an integrated PS/2 port, but I'm not using
it. The mouse on this system is a serial mouse

Comment 2 Chris Ricker 2003-04-03 14:17:15 UTC
Seeing this with kernel-2.4.20-8smp on RHL 9 as well

Comment 3 Pete Zaitcev 2004-01-20 04:36:18 UTC
Does Fedora do the same?

Comment 4 Pete Zaitcev 2004-01-20 04:37:01 UTC
Dax, what are you doing on cc:? Do you have a reproducer for this?

Comment 5 Dax Kelson 2004-01-20 04:50:22 UTC
No, I was just curious.

Comment 6 Chris Ricker 2004-01-20 12:55:28 UTC
alphas & betas up to the release of Fedora Core 1 did (Aug / Sep / Oct
kernel releases)

I've not tried any of the most recent Fedora kernels since I moved
cross-country in November and that machine hasn't (yet). It should be
getting here at the end of this month, though, so I'll update then....

Comment 7 Pete Zaitcev 2004-04-19 16:08:52 UTC
Please retry with either FC1 or FC2 Test releases (2.6 kernel).

Normally these symptoms point to BIOS trying to emulate
legacy keyboard under our feet though, so I don't think
I can do anything. But let's not discount a possible SMP

Comment 8 Chris Ricker 2004-04-19 20:37:45 UTC
Still does it with FC1 (2179 kernel)

Comment 9 Pete Zaitcev 2004-04-19 22:52:35 UTC
Have you tried a different keyboard? Trying to split hid off uhci here.

Comment 10 Bugzilla owner 2004-09-30 15:40:24 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project ( maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at:
