Bad commit appears to be:
commit 6f461f6c7c961f0b1b73c0f27becf472a0ac606b Author: Bruce Allan
Date: Tue Apr 27 03:33:04 2010 +0000 e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errata
I built an OpenSUSE 11.3 kernel with just this patch reverted and the problem no longer occurs.
Just to confirm this happens in the upstream 2.6.36-rc3, right? 19833b5dffe2f2e92a1b377f9aae9d5f32239512 upstream does not fix it? If it still happens upstream please report it to LKML and CC the Intel folks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

See comment 6. I tried it twice. Second time to double check I didn't mess up. I'll try it a third time ... but my feeling is, no, it doesn't help.
Right, but did you try it in the upstream Kernel (e.g. 2.6.36-rc3)? If it is still happening in the upstream Kernel then can you report it upstream? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Yes, I got that. I'm checking ;-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
