Each time the SSH dies before a umount NFS, I have to umount -f and I get a crash (only sysrq works). Actually, the crash occurs a few seconds after umount -f. It seems that killing SSH by hand does _not_ lead to crash. But a long network failure does. I remember seeing this bug several times with all stable releases from 2.6.7 to 2.6.11. I didn't try with earlier versions. I didn't see anything in the logs (after reboot). But I can't be sure there was nothing in dmesg since I didn't get a chance to chvt 1 and see console messages before rebooting (with sysrq). Do you have any idea how to debug this ?
