I have been troubleshooting reboots over the last weekend, I think I
might have enough clues now to get some useful hints from an expert.
FreeBSD 5.3-release (see dmesg below for details)
The problem seems to be with trying to run with 1.5GB vice 512MB of RAM.
The system has not had problems so far when I only leave the 512MB stick
in. When I add the 1GB stick the system will reboot at specific times,
for example, while trying to launch KDE3 or trying to make OpenOffice
(always reboots at "Extracting for openoffice-1.1.2-1"). I do not see
any panic in the messages log, the system just silently reboots.
I initially installed FreeBSD with only the 512MB stick in.
The memory itself seems fine; memtest86 detects no errors.
At boot time all the memory is detected:
real memory = 1610547200 (1535 MB)
avail memory = 1568432128 (1495 MB)
Running "memtest all" only seems to find 512MB to use. It evidently
makes no assumption about how much memory is there, starting by trying
to malloc 4GB and reducing the amount gradually until it finally
successfully mallocs 512 MB and eventually manages to lock 413 MB
(failed due to "insufficient resources" above that). The tests on the
413 MB do pass.
I have rebuilt the kernel with VM_KMEM_SIZE_MAX=419430400 as suggested
in the FAQ. No change.
Would setting MAXMEM to 1572864 help? I am not sure since the correct
amount is reported by FreeBSD at boot, and right now trying to make the
kernel with that option seems to be another case that reboots the
machine (i.e. the make process itself reboots the machine) so I have not
tried it yet (guess I would have to remove the 1GB stick to make the
new kernel and then put it back to try it out).
Thank you for any help.
