Hello,
I ran different versions of gnumach in different versions of qemu. I got the
Hurd image for qemu from
http://ftp.debian-ports.org/debian-cd/K16/debian-hurd-k16-qemu.img.tar.gz. The
gnumach in the original image runs well in qemu v0.9.1. I built the gnumach from
the master branch of the git repository and got the error:
start /hurd/ext2fs.static: hd0: irq timeout: status=0xd8 { Busy }
hd0: disabled DMA
hd1: disabled DMA
ide0: reset: success
Hurd server bootstrap: ext2fs.static[device:hd0s1] exec init proc authswapon:
/dev/hd0s2: Linux 2.2 swap signature v1, 532220k swap-space (excludes 8k at end
of partition)
Then I tried to run hurd in qemu v0.12.3 because I need the e1000 NIC card.
Again, I first ran gnumach in the original image and got the message as follows:
task loaded: /lib/ld.so.1 /hurd/exec start /hurd/ext2fs.static:

Then I ran gnumach in the git repository, and got similar errors:

It seems that when using the gnumach from the git repository, DMA is disabled
and the system is very slow especially when I compile programs. And the system
hangs very easily.
Are these known problems? I didn't find any discussion on this mailing list. Is
there any easy fix?
Best regards,
