This is rumored to be a known problem. Since I've seen it a lot recently
and am going on vacation, here's what I know in case it helps. The problem
can manifest on one machine and not another with the same bits. It can
come and go as the size of code in arch/parisc/kernel changes. The
problem shows in the boot like this:
Attempting to execute '/sbin/init'
PSW : 0004000b GR 1 : c0128800 GR 2 : c0029390 GR 3 : 00000000

SR4 : 00000000 SR5 : 00000000 SR6 : 00000000 SR7 : 00000000
IAOQ : c0028e5c c0028e60
bad address a000002c (code 15)
Kernel panic: bad address
adb on the IAOQ address says:
do_generic_file_read+16C: LDW 8(r21),r19
which is consistent with the value in r21 (a0000024). This is
inside a call which I believe is called eventually from do_execve()
called within init/main.c:init(). I didn't track down do_execve().
