e1000e probe failure on 2.6.34 and higher, Intel MB

Hi,

http://bugs.launchpad.net/bugs/591707

I've a bug where e1000e works with Lucid (2.6.32), but fails to probe 
with 2.6.35-rc2. The output is mighty terse.

[   28.193628] e1000e 0000:00:19.0: PCI INT A disabled
[   28.193740] e1000e: probe of 0000:00:19.0 failed with error -3

The full dmesg logs are at 
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/591707/comments/23 
and 
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/591707/comments/24

The reporter says that it also fails with 2.6.34. The report has logs 
showing that it works with 2.6.32 and fails with 2.6.35-rc1. I've 
requested the reporter install a vanilla -rc2 kernel from 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-rc2-maverick/linux-image-2.6.35-020635rc2-generic_2.6.35-020635rc2_amd64.deb, 
but I do not expect different results given that the only change from 
rc1 to rc2 is 'e1000e: change logical negate to bitwise' (which is not 
germane to probing).

This appears to be an Intel OEM MB as far as I can tell from the DMI. It 
was new in April so is unlikely to have flash corruption issues such as 
those observed with 2.6.24.

Any suggestions on why the probe silently fails? None of the module 
params look like they'll make a difference.

This looks like a BIOS problem.  It looks the interrupts aren't being setup correctly in the system and the driver can't request them.  Why it's working on some kernels and not others may be do to some BIOS setup with the interrupts that happens in one and not in the other.  Does the MB have the latest BIOS on it?  Please make sure and test it again if not.


Cheers,
John
