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!

Test kernel with proposal applied patch
Hello, I built and attached the test kernel package with applied patch to solve
the problem. Could you please test the package on target machine and report
here if the bug is solved?
Hans-Gerd, your comments are not automatically posted to BZ when entered in
I'll forward your message to BZ for you:
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

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.

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.

Is it necessary to attach posted patch here? I'm a newbie in Red Hat.

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:
Thanks a lot.
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, I will send a corrected patch into mailing-list.
