[Qemu-devel] OS/2 lockups during bootup

[Qemu-devel] OS/2 lockups during bootup

[Johannes Martin]

Hi everybody,

I'm having some trouble booting up OS/2 in qemu (CVS, Linux host). OS/2
frequently hangs during bootup when loading one of the following device
drivers:
	IBM1FLPY.ADD
	IBM1S506.ADD
	IBMIDECD.FLT
	IBMDASD.DMD

The lockup may occur randonmly in any of these drivers or not at all. When
I reboot OS/2 or restart qemu a couple of times, I usually get past these
drivers eventually. It takes patience though.

I know that something has gone wrong when qemu starts using 99% of CPU
time while loading these drivers. I assume the drivers are in some kind of
loop waiting for some event to happen - I guess it's a timing problem and
sometimes things don't happen in the right sequence.

Any hints?

Thanks

[Qemu-devel] OS/2 lockups during bootup

[Nathan Kunkee]

Johannes,
Over this last weekend, I was able to install and boot OS/2 (v3, blue spine) 
through the latest CVS version of CVS. I encountered two problems: After 
copying the last base disk (6 I believe), the installer asked that I eject 
the disk and press enter. Somehow in the process of switching to the monitor 
and back, I could never get that last enter pressed. It turns out that there 
was nothing after that; all the needed files had been copied. The other 
issue I found was even though I had a blank disk image file, OS/2 did not 
install a master boot record. I had to boot with a Win 95 boot disk to add 
one. (fdisk /mbr)  I do see  CPU spike and fall during the load of 
IBM1S506.ADD.

For the rest of the list, I have not had any success with loading sound 
support. I'm using Win XP as a host.. Any thoughts?

Hope that helps, and thanks in advance.....
Nathan

I just tried it again with the latest CVS. I, too, usually see some spikes
in CPU load when those drivers are loaded, but they are rather short in
the "working" case. Frequently, the cpu-usage remains at 99% and that's
the end of it.

I'm running OS/2 Warp 4 with fixpack 15 and device driver fixpack 2
(though the lockup occurs without the fixpacks as well). It does not seem
to matter whether I use -isa or not (not sure whether that affects the
IDE/FDC controller emulation).

:(
