Bug#420398: linux-image-2.6.18-4-686: kernel BUG at fs/fuse/control.c:82!
Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-12
Severity: normal
I have been using sshfs over fuse for quite some time without
problems. Noticed a high load this morning, and found the oops below.
Known fixed issue upstream: http://lkml.org/lkml/2007/1/29/210 ??
I'm not sure of what triggered this oops. At the time of the fault,
the system was pretty idle, and I don't think my net connection or the
ssh connection went down at the time.
invalid opcode: 0000 [#1]
SMP
