As the log was most probably too big to pass majordomo, i've put it here: http://permalink.sur5r.net/1/linux-3.2.51-resize2fs-1.42.5-hung-sysrq-t.log Please tell me whether you need anything beyond that (ssh access would be possible) or whether I can put that machine back to production. After a forced reboot, will an "fsck -f" be sufficient or should I create a new filesystem? It was a newly set up backup target so I could scrap it if necessary.
