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=0xa0000000 dkcsum: BIOS drive 0x80 bsd_dev=0xa0000200 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]).
