| |
I got an Oops in 2.0.25, quite similar to what Franz <franz@azstarnet.com> just reported. The computer was most likely idle at that time. As in Franz's case, the compur continued working several hours after the Oops, although many commands such as df and sync froze, and couldn't be killed.

Previous crash before this one happened 9 days ago. It was different. No user processes answered, but kernel answered to pings and accepted tcp-connections. SCSI errors were scrolling on the console, probably of target 6 as well. Nothing in logs.
