I've repeated it, and it definitely says 332, so don't blame me for that one <g> > Did you see any "dummy wdunwedge" messages before you dropped into DDB, > or any other messages at all?

I have to ctrl-alt-esc to get back into the debugger. A few other lines which may be relevant, everything else was pretty much the same as last time: _worklist_insert(head=f1a049a0,item=f0fa0280) at _worklist_insert+0x10 [../../ufs/ffs/ffs_softdep.c:402] _softdep_disk_write_complete(bp=f1a049a0) at _softdep_disk_write_complete+0x29d [../../ufs/ffs/ffs_softdep.c:3012] _biodone(bp=f1a049a0) at _biodone+0xab [../../kern/vfs_bio.c:1915] The disk light did actually go off after a while, but it came on again as soon as I typed (c)ontinue, so it's stuck somewhere. -- Ben Smithurst : ben@scientia.demon.co.uk : http://www.scientia.demon.co.uk/ PGP: 0x99392F7D - 3D 89 87 42 CE CA 93 4C 68 32 0E D5 36 05 3D 16 http://www.scientia.demon.co.uk/ben/pgp-key.html (or use keyservers) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
