Hi,

I just want some thoughts on this:

In the last 24 hours my workstation is been going nuts, whereas it has been
running along nicely for weeks before.

The things that kept me bugging today were these happy messages:

Dec 20 10:51:14 chronias /kernel: Unexpected busfree.  LASTPHASE == 0xa0
Dec 20 10:51:15 chronias /kernel: SEQADDR == 0x157
Dec 20 10:51:15 chronias /kernel: (da1:ahc0:0:1:0): SCB 0x5 - timed out while
idle, LASTPHASE == 0x1, SEQADDR == 0xc
Dec 20 10:51:15 chronias /kernel: (da1:ahc0:0:1:0): Queuing a BDR SCB
Dec 20 10:51:15 chronias /kernel: (da1:ahc0:0:1:0): Bus Device Reset Message Sent
Dec 20 10:51:15 chronias /kernel: (da1:ahc0:0:1:0): no longer in timeout, status
= 353

After which page and swap process were running wild.

The weird thing is, these HD's (two SCSI Quantum Fireballs) have been checked, the
HA (AHA 2940UW) is likewise in good shape and the memory chips have been tested as
well... The mainboard is also in good shape and is cooled by a few fans (3) which
all work, including the one on the CPU.

The circumstances when this happened was when I did a locate.updatedb at the same
time as downloading a PDF file to the HD, and then I opened a mailbox at which
time the whole time went haywire...

Unfortunately I wasn't able to write down the pager messages since they went by
with warpspeed 9 and they weren't logged in /var/log/messages =\

Does anybody have any ideas what to check to narrow down the problem?
