SubjectRegression 2.6.36 - driver rtl8169 crashes kernel, triggered by user app
This is the 3rd time I send this, and I did not get any answer.
I thought *regressions* are a bad thing that would be handled quickly?

Dear list, I've hunted down a bug which does *NOT* occur in kernel from openSUSE 11.3, but crashes stock kernel 2.6.36
triggered by a user!

It's actually very simple. From my desktop (kernel 2.6.36) I "cd" to an
NFS4 share, where a xz compressed image of Win7-64.iso.xz is located.

# cd /q/iso-images

and then I try to uncompress it there (as user, not root!):

# xz -kv Win7-64.iso.xz

With kernel, this runs with ~41MiB/s without

With kernel 2.6.36, it runs at ~26MiB/s, and while doing so, dmesg shows
a lot of noise about r8169 complaining:

Here are 2 pictures of different crashes:

Neither the dmesg-messages nor the crash happens with kernel as delivered by openSUSE 11.3, but it always fully
crashes 2.6.36. I've retried about 10 times, it *never* finished to
uncompress the ~3GB image. At around 500-1000MB the kernel was gone.

I'm sure someone knows how to fix it. :-)

mit freundlichen Grüssen,
