OK.  I dug out my old Everex Freestyle A-10 (updated to 16MB).

With a 4MB flash card, I can boot to the point where it tries to mount
root and fails [dmesg1 below].

If I boot off a 4MB flash, then remove the flash and insert a 1G IBM
Microdrive, I get:
...
root on wd0a dumps on wd0b
pcmcia0: card irq 3
panic: TLB out of universe: ksp 0xc2667fd8 epc 0x8007c578 vaddr
0xc0001000
Stopped at      0x8016e078:     jr      ra

db>

which is similar to crashes that I've seen in the past.  Full dmesg is
in dmesg2 below.

Also note, before people drool over this device, the cpu speed is
wrong.  It should be more like 55MHz, not 589.824MHz.  I'm not sure
why it is off by a factor of 10 like that.

The kernel is from the end of October, so before the cache rototill
that was done this month.

This is mostly an FYI.  The machine is too much of a pita to boot to
be useful on any kind of regular basis.  The boot process took sevearl
tries :-(.  I can't remove the flash card before hitting OK to boot
and have it boot.

Comments?
