Hi,
I mailed -stable a while back (see below), but have
had no reply. I'm getting reproducible crashes (on my
machine at least) in ffs_blkpref() when under heavy load.
This machine is supposed to be a file server and, so
far, I've not got any confidence in it!
Any help would be very much appreciated!
Stewart.

Hi all,
I'm running -stable, cvsup'd as of yesterday (14/06/01).
I've just set up a RAID-5 array using vinum on 40GB IDE drives.
All went well until I tried copying data to the drive from a
sharity-light mount at which point, the system panic'd!
I managed to get a dump (see below), but interestingly
savecore'ing to a different drive (a SCSI Seagate drive) also
panic'd the machine -- kernel.GENERIC has, so far, picked the
dumps up no problem, but my custom kernel just gets oh-so-close :(
I remember reading a past thread; I've got two fxp's and
an on-board AIC-7895, so I wondered if this might have something
to do with it?
Of the dumps that I've managed to recover, all of them seem
to falter at ffs_blkpref, hence the subject.
Please find attached a trace, dmesg, and kernel config file.
I have the vmcore file(s) available, but ask if there's anything
else you need and I'll see what I can do...
