I forgot to mention: AFS 1.25 crashes on shutdown on frobnitz (or,
anyway, when you do a "shutdown -r now" it doesn't shut down afs until
"syncing filesystems" and it gets a vm fault after a few AFS
msesages), so we need to fix that even if we get the machine to boot
correctly.
John thinks the rebooting problem may not be an IRQ problem even
though it's probably a problem with the ethernet controller. He
suggests we try moving the serial port to a different IRQ or disabling
it; Yoav, do you know where the motherboard instructions for the
machine might have gone?
It's probably also worth noting that I hacked the kernel (in the
opssrc tree, options BIOS_REBOOT, not enabled in ATHENA-DIALUP, files
affected are arch/i386/i386/{locore.s,machdep.c, code stolen from
arch/i386/boot/asm.S) to go to real mode and reboot using interrupt
0x19, and that did the same thing as the normal reboot code
(i.e. boots fine unless you configure the le device, hangs after
booting if you don't configure the le device).
(In both of my tests, in addition to ifconfig'ing the le device I also
did a "ping glacier" for a second or two.)
