Public bug reported:
Description: Ubuntu 8.04
Release: 8.04
bochs:
Installed: 2.3.6-2ubuntu1
Candidate: 2.3.6-2ubuntu1
I've been using bochs to develop my own simple little OS. With the
upgrade to 8.04 now bochs just segfaults when it seems to jump into the
rom bios code. I've been using bochs for this without fail since Ubuntu
6.10.
Config snips:
romimage: file=$BXSHARE/BIOS-bochs-latest, address=0xf0000
vgaromimage: file=/usr/share/vgabios/vgabios.cirrus.bin
vga: extension=vbe
In the output logs from bochs the things of interest that I'm seeing
are:
...
[MEM0 ] >>PANIC<< ROM: System BIOS must end at 0xfffff
...
[CPU0 ] SLDT: not recognized in real or virtual-8086 mode <- This is repeated
a monster amount of times
...
[VGA ] character height = 1, skipping text update
[CPU0 ] prefetch: EIP [00010000] > CS.limit [0000ffff]
[CPU0 ] SLDT: not recognized in real or virtual-8086 mode
[CPU0 ] prefetch: EIP [00010000] > CS.limit [0000ffff]
[CPU0 ] >>PANIC<< prefetch: getHostMemAddr vetoed direct read, pAddr=0x000bfa0d
The last part is repeated about 5 times before the panic. Note that it
doesn't even seem to get to the disk image and I've never seen bochs do
anything like this before so I'm at a loss :(
