[9fans] plan9 on qemu problems...

[Joseph Stewart]

I'm running plan9 on qemu under win32 (compiled with MINGW).

I applied the patches suggested in this list several days ago
(thanks!), and booted from CD and installed into a HD image... all
seemed fine until trying to reboot into the newly created HD image.

I then see:

dev A0 port 1F0 config 0040 capabilities 0300 mwdma 0000 udma 201F
dev A0 port 170 config 85C0 capabilities 0200 mwdma 0103

and qemu seems to "go to sleep" (meaning plan9 never starts up, no
error messages, etc).

Here's the line I start qemu up with:

qemu -L bios -hda p9hd.img

Anyone else having problems like this?

What other debug info might I provide that would help fix this?

Thanks!

I found the Win32 Qemu to be very flakey, sometimes it would work,
sometimes hang as you describe. It was downloaded, not compiled from
scratch. I found some problems by going into the monitor (ctrl-alt-2)
and dumping the instruction stream at the current pc (x/10i $eip)
then using acid on the kernel binary to see where it was looping
(e.g. in the ne2000 driver if you don't have the 'nodummyrr' option).
