I have been running several versions of FreeBSD
on several machines here, with IDE disks, but am
now having many panics, usually due to page faults,
on the first machine where the only disk is on a
SCSI adapter. The usual message involves "page not
present", but there have been some "double faults"
also.
I had lots of problems doing a network install
using the install diskette from the 2.1.5R set; the
MTBF was shorter than the time to get the
distribution. Now I am running 2.2-961014-SNAP,
and the system can stay up for hours, though ftping
a 300 MB file will usually bring down the machine
after about two thirds of the file.
Some information:
Dell Dimension DM 466, 486DX2-66, 16 MBs
AHA-1542CP (w/Plug n' Play disabled)
Seagate ST1523ON - 4 GB divided into 2 GB partitions
system was in first partition, used default "auto" slicing
(4 slices, /, swap, /var, and /usr)
3C509 NIC
This system worked reasonably well under DOS.
I suspect the AHA1542 board may be involved. I
would appreciate hearing from any experts as to how
this card should be configured. I had been leaving
the BIOS enabled, and booting as BIOS drive 1
"1:(sd(0,a)".
It appears to me that the handbook
could use a section with info like:
"Mumbleco XXX board - must enable BIOS but disable
extended translation"
Am I correct that there is not place where such
config info has been gathered? (This is why I am
appealing to the distributed USENET database).
I have saved some crash dumps; I have not yet
tried to build a kernel with symbols and debug
the dump, but if any experts want the numbers
from a traceback, I could send them along.
Thank you for any information.
