Description Andreas Reis 2015-08-14 14:32:56 UTC
Created attachment 184921 [details]
dmesg picture

Happens withing 10min while eg. torrenting. net-next from a few days ago was fine.

Picture as ssh hangs and dmesg to disk lands in nirvana instead.

Checked via reverting this commit, which allowed me to merrily torrent without lockup again. This does not 100% prove that it was actually the cause, ofc.

Since that isn't yet in net-next, I didn't see it… I'll test again with it on Sunday.

Haven't seen the lockup with the missing commits from net applied to net-next, so closing.
