I've been having a large number of these panics in the last few days
after replacing significant parts of my system.  In each case, the
system appears to die when writing a large file (the text of "The
Complete FreeBSD", about 40 MB).  This isn't surprising, I suppose.
Dumps and debug kernel are available, but don't show me much.  I'm
still researching this one, but if the following list of changes
catches anybody's eyes, I'd be interested in hearing from you.

First, the changes:

Old				New

P54C, 133 MHz			K6/233
Old motherboard,		IWill P55XB2, Intel TX chipset
  forgot the name
96 MB SIMM memory		128 MB mixed EDO SIMM and SDRAM
Adaptec 1542A and		Adaptec 2940UW and 2940 host adapters
  2940 host adapters
IDE system disk			IDE system disk

I've checked all sorts of things, including:

changing the CPU back (still panics)

playing around with the host adapters (inconclusive).  It looked as if
the 2940UW might have been the culprit, since I was writing on a disk
on that adapter, but once it corrupted the IDE /usr, and after
swapping around to put /home on the 2940, it still failed.

upgrading from last week's -current to today's -current.  No change.

Any ideas?

Greg
