Hi Mikael, I've since changed too much around my system to be certain, but would suspect the bug to still be there. I'll see whether changing my config to use SLUB retriggers the bug when uncompressing a huge file (but I'm running with only 14 MB noe, which makes traversing the entire VM metadata a lot faster).

The first one was inconclusive (pointed to a harmless commit), but the second one ended up with: # first bad commit: [ac4de9543aca59f2b763746647577302fbedd57e] Merge branch 'akpm' (patches from Andrew Morton) That's a big pile of VM changes, so I think it could be the culprit. Are people still seeing the kswapd bug with current kernels? I've stayed with the 3.10 kernel series on my aranym VMs, except for the one VM that did the bisection tests. /Mikael
