after the block layer regression seemed to be fixed, the machine
appeared to be running fine. But after putting some disk I/O to the system
(PowerBook G4) it became unresponsive, I/O wait went up high and I could
see that the OOM killer was killing processes. Logging in via SSH was
sometimes possible, but the each session was killed shortly after, so I
could not do much.
The box finally rebooted itself, the logfile recorded something xfs
related in the first backtrace, hence I'm cc'ing the xfs list too:
du invoked oom-killer: gfp_mask=0x842d0, order=0, oom_adj=0, oom_score_adj=0
