I have been having a lot of bad crashes recently (basicially since I
installed PatchKit 0.2). There seem to be two types of crashes:
1) The file system dies. Programs that are running keep running, but as
soon as they access the filesystem they block forever. I can reboot the
machine w/ the 3 finger salute, so I usually do that. Usually I loose a
few of the most recently accessed files (one of which is the user file
for my bbs, which sucks).
2) Everything just dies. I can usuaully switch virtual consoles and
give it the 3 finger salute, but not much more.
I have been experiencing crashes of the first type since I installed
386bsd, but the second has just cropped up since I installed PatchKit
0.2. I am also using syscons (I couldn't get pcvt to work, just hard
locked the machine on bootup). Normally I can live with a crash after
two days of uptime (just get into the habit of rebooting daily), but
recently things have started crashing a few times a day (about 50% of
each type). Today the file system crashed so hard that I lost my
bootblock (and had to spend a few hours learning how to reinstall them
w/ disklabel).
I assume that the first one is related to the wd.c driver, but I haven't
seen any replacements that address this issue. Looking through the
386bsd.BUGS list it seems they mention some scheduling problems that
sound like they could be causing the crashes too. I haven't seen any
patches for that code outside of the patchkit though. Anything I can do
about this?
Here is my machine configuration:
Mitsubishi MP386dx/16 with 80387
120 meg Talon (samsung) IDE hard drive
6 megs of memory
Paradise VGA card (256k)
Amiga 1000 as a terminal
3c503 for networking (off of AUI port)
Here is my 386bsd configuration
Standard install +
Kernel patched to PK0.2 (using all patches that would install without
source for the rest of 386bsd, and without the patches for things that
didn't affect my system).
Syscons for virtual consoles
Little hack on the 3c503 driver to use AUI port instead of BNC
5 meg swap
Any help (or even just some explanations of what is going on) would be
much appreiated. The OS is great, I just don't have the time personally
to look for the bugs and fix them.
thanks,
alex
