Hi.
I saw that my 4-CURRENT box from 8 February dropped to ddb
after my last make world. I'm not sure what the trap indicates
"caused" the problem.
The error is
"Kernel type 12 trap, code=0
Stopped at vfs_msync+0x20 : movl 0x28(%ebx),%edi"
Does anyone know what this means ? The machine was idle
at the time - I'm the only user, and it isn't used as a
public access server.
I am using softupdates and NFS (not heavily though).
I haven't seen anything like this on -current or -hackers,
and searching the mailing lists didn't reveal anything
relevant.
My kernel config and dmesg is listed below.
TIA!
dmesg
