Description Hans-Gerd van Schelve 2007-03-19 09:40:20 UTC
We have some ThinkPads T60 and X60 with internal MiniPCI UMTS / HSDPA Card. The Card is a Sierra MC8577 (USB Id 1199:6804). In RHEL5 there is a sierra Kernel Module which supports this card in general but Lenovo has it's own Product ID (6804). In Fedora 7 with Kernel vmlinuz-2.6.20-1.2986.fc7 there is a newer Sierra Module that supports the card fine. Without the sierra Module we can use the card with the usb-serial Kernel Module but only with about 40 KB/s in Downlink. With the Sierra Module on Fedora 7 we get 140 - 150 KB/s!

Comment 10 Issue Tracker 2007-08-03 10:53:18 UTC
Hans-Gerd, your comments are not automatically posted to BZ when entered in IT. I'll forward your message to BZ for you: Ivan, i tested your kernel on my x60. I get about 140 KB/s when downloading a file, about 45 KB/s when uploading and ping round trip times from 140 ms. The lsmod shows that the sierra module is loaded. So I think it's all OK. -- Hans-Gerd This event sent from IssueTracker by navid issue 118685

See also bug 247884.
Comment 13 Pete Zaitcev 2007-09-19 01:14:15 UTC
Created attachment 198981 [details] Ivan's bigger backport after a review turnaround Ivan neglected to attach the patch which I acked, so doing it now. However, now that I looked at option.c for bug 249660, I think we should be a bit more proactive with the port. The original Kevin's driver had a few issues such as the use of -EINPROGRESS, since fixed.
Comment 14 Pete Zaitcev 2007-09-19 02:58:56 UTC
Created attachment 199081 [details] Same as before, but with few more IDs removed On second thought, Ivan had a good idea. The current sierra wants to be too modern with dynamic URBs and everything. It's a bridge too far.

Created attachment 249401 [details] The proposed patch Hello, I would like to ask you to test again a test kernel package. We found some issue that had to be solved. So we need to know if the current solution works well. Could you please test this kernel package and report a feedback? You can find it on: http://people.redhat.com/ivecera/bz232885/ Thanks a lot. -- Ivan
Comment 19 Navid Sheikhol-Eslami 2007-12-06 09:39:20 UTC
Ivan, the customer now requires the device to work on T61 so I had to add the correct USB IDs to the patch for USB_DEVICE(0x1199, 0x6813). With this tiny modification to your patch, the customer's feedback was positive. Thank you. -- Navid
Comment 20 Ivan Vecera 2007-12-06 10:59:36 UTC
Thank you Navid, I will send a corrected patch into mailing-list.

Comment 22 Jay Turner 2007-12-13 14:24:19 UTC
Do we have access to hardware for testing?
Comment 23 Navid Sheikhol-Eslami 2007-12-13 14:49:00 UTC
Jay, I have a T61 here in EMEA available for testing. -- Navid
Comment 24 Jay Turner 2007-12-13 15:21:36 UTC

Hi, the RHEL5.2 release notes will be dropped to translation on April 15, 2008, at which point no further additions or revisions will be entertained. a mockup of the RHEL5.2 release notes can be viewed at the following link: http://intranet.corp.redhat.com/ic/intranet/RHEL5u2relnotesmockup.html please use the aforementioned link to verify if your bugzilla is already in the release notes (if it needs to be). each item in the release notes contains a link to its original bug; as such, you can search through the release notes by bug number. Cheers, Don
