Hi,

i decided to do some cheating :) and skipped the breakpoint where it used to
stop (0x40200). (by the way, hitting 'c' wouldn't continue at all and keep
executing the same instruction over and over again). This time it seems it behaves as expected:


Uhm, it looks to me that you ran qemu with the -kernel option again (I can tell because the dump exhibits a few bugs that are characteristic of the qemu loader.) This makes qemu itself load the kernel and not rely on the boot loader that's on your bootloader.

I was expecting you to run "qemu -S -s -hda /dev/hda -snapshot", which you previously said when run (without the -S -s) options reproduced the problem.

After taking the dump, please do:

delete
c

... to verify the problem is reproduced.

Thanks,

-hpa
