Yes, I know 4.11 is EOL'd at the end of this month, but hopefully
someone can shed some light on this problem anyways. I simply don't
have the knowledge of what's going on on a low-level to determine
the cause.
I do have serial console on this box, and after enabling some
debugging for the ahc(4) driver a few months back, was able to
get something intelligent out of the system regarding SCBs this
morning. This may not be useful (or the cause), though. I also
cannot enable drop-to-DDB-on-serial-break because our Portmaster 2
has been known to send a serial break on rare occasion. :-(
Every so often (sometimes hours, sometimes months -- usually months),
the 4.11 box we have "locks up" in the sense that both NICs on the
box stop working, and the SCSI controller also appears hung. This
problem has existed for a couple years; it's not specific to 4.11
(versus 4.10 or 4.9).
I have to hard reset or power cycle the box to get it working again.
The problem will continue indefinitely until the machine is reset;
meaning it does not recover on its own. Naturally this means quite
an ugly fsck when the machine comes back up.
The initial symptoms are:
fxp0: device timeout
fxp1: device timeout
ahc0: Timedout SCBs already complete. Interrupts may not be functioning.
Hardware:
* 2x Pentium III 933MHz
* Tyan Tiger 200
- VIA NB/SB chipset (probably the cause of all this :) )
- Mainboard running latest BIOS
- 2x Intel 82559 on-board NIC
* 512MB RAM (ECC; has built world for years no problem)
* Adaptec 29160 U160 controller (physical card, not on-board);
not sure what Adaptec BIOS revision (anyway to check via FreeBSD?)
* Hard disk is a single 16GB U160/SCSI-3 drive
* Kernel is SMP

I can include my kernel configuration if need be, but it's fairly
standard.
