Hi,
we already had words on lkml about this bug with sky2 driver.
I was having problems, and you told me to use the disable_msi=1
parameter to see what happens. After a couple of hours of testing with
heavly ethernet load, I answered you it had fixed the problem. I was
wrong. Now, it takes much more time to crash. Most of time, I can't even
see what happens beacause the box is completly frozen. But after several
crashs, I only had my keyboard locked, usb unpowered, and ethernet
interface down, I finally had the possibility see that :

It's exactly the same error than before. What do you think of this
trace ? Is it related to sky2 driver or acpi ? Did you add debug output
since 2.6.19.2 (version of the kernel I'm using) that would help to fix
that bug ? What can I do to help to fix the bug ?
