SubjectReiserFS panic (faulty hardware?)
DateTue, 6 Jul 2004 13:25:24 +0200
Hello, hackers.

So our server decided to stop being useful an hour ago, right when my
vacation had begun. A quick 'dmesg' told me that a ReiserFS panic had
occurred. I fed this thing through ksymoops, but got no wiser from the
result. Maybe you can read something more out of this. Any pointers
(even 'faulty RAM, replace' or a simple 'sod off' in Viro style) are 
welcome.
