I've tried patches with post 2.6.32-rc4 kernel and after second suspend-resume cycle I got typical "order:5" failure. However, this time when I manually tried to bring interface up ("ifup eth0") it failed for 4 consecutive times with "Can't allocate memory". Before applying these patches this never occured -- kernel sometimes failed to allocate memory during resume, but it *never* failed afterwards. I'll go now for another round of bisecting... and hopefully this time I'll be able to trigger this problem on different/faster computer with e100-based card. > although that driver has already been fixed by not making high-order > atomic allocations. Driver has been fixed? The one patch that I saw (by davem[1]) didn't fix this issue. As of 2.6.32-rc5 I see no fixes to e100.c in mainline, has there been another than this[1] fix posted somewhere?
