Libretto 70CT Debugging
Hi Misc,
I'm stumped (again) my Toshiba Libretto 70CT has not been
able to boot a kernel since 4.3, this is know issue [1],
I have just compiled a kernel with option DEBUG and option
WDCDEBUG to see if I can track down the issue.
I disabled softraid at the UKC> prompt (due to a hint from [2])
The kernel integer divide fault trap occurred again, but there was some
additional debug info which I have not seen before:
root device softraid not configured
dkcsum: bootdev=0xa000
dkcsum: BIOS drive 0x80 bsd_dev=0xa200 checksum=0xc31f9477
kernel: integer divide fault trap, code=0
Stopped at cpu_switchto+0x76: popl%ebx
Not sure if this sheds any further light on the problem?
Is there any other debugging information I can get?
The dmesg, trace and ps are at the end of this email.
Any clues appreciated, and as a side note the bsd.rd kernels boot
fine (with the exception of the 4.8 bsd.rd that had the "memory"
clobber to lidt inline asm issue [3]).
Thanks
Fred

Re: Libretto 70CT Debugging
Hi,
with all this libretto thread, I backed out my old Libretto 60, but I
can only confirm that it also has the same problem:
