Hi Sam,

Can you comment if this existed with the 2.6.26 kernel available previously for Intrepid?

Heh, ok thanks Sam. I'll hold off on tagging this 'regression-2.6.27' which is what the kernel team will likely use to examine reports when they are deciding to stick with 2.6.27 or not. Thanks.

This bug is almost certainly the same as that reported and fix-offered upstream. Please see
http://lists.linux-wlan.com/pipermail/linux-wlan-devel/2008-August/003861.html

I get the same Ooops in Intrepid-alpha-5. I suspect applying Richard Kennedy's offered patch will resolve this. Richard is an upstream developer who has contributed to linux-wlan-ng before.

Hi All,

There is a serious bug which may affect some people subscribed to this report so I wanted to pass along the information. Due to an unresolved bug in the e1000e driver in the 2.6.27 Linux kernel, this driver/kernel should not be used on Intel ethernet hardware supported by the e1000e driver (Intel GigE). Doing so may render your network hardware permanently inoperable.

Older Intel ethernet hardware which uses the e1000 driver is not affected by this; however, some hardware which used the e1000 driver in previous Ubuntu releases, such as hardware that uses a PCI Express bus, has been moved from e1000 to e1000e in the latest kernel releases. If in doubt, do not use this driver/kernel and subscribe to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/263555 to be notified when the bug is fixed.

Thanks.

I can confirm the Oops in 2.6.27-4-generic, i.e. the current Intrepid kernel, when the p80211 module is loaded (which happens when Prism based wireless cards are present).

I then compiled the kernel myself, and applied Richard Kennedy's patch from
http://lists.linux-wlan.com/pipermail/linux-wlan-devel/2008-August/003861.html

With this patch applied, the modules load and the card starts functioning.

Without this patch Prism hardware will be rendered useless. Note also 2.6.26 was okay, so this bug ought to have the regression-2.6.27 tag.

I would say comment 7 is questionable, this is a regression whether we like it or not.

I'll have to kernel team look at the patch posted upstream upstream to consider pulling it in prior to Intrepid's kernel freeze. Thanks.

Patch committed upstream Edit (2.8 KiB, text/plain)

Upstream has now committed a slightly cleaned up version of the patch in their git tree. I have attached the committed patch here for convenience.

I can confirm the same problem, after updating to intrepid beta. Kernel 2.6.27-5 Oopses as soon as the prism2 module gets loaded and initialized.

I have a Flybook A33i with 124a:168b AirVast wifi module (it's a sort of "virtual" usb device)

Booting with 2.6.24-1 it works flawlessly.
