Package: qemu-kvm
Version: 0.13.0+dfsg-2
Severity: important
Hi,
See [1] for the war story. When I boot the HURD without passing
-no-kvm-irqchip on the command line, the system usually will
print
hd2: irq timeout: status=0x50
hd2: irq timeout: status=0x50
hd2: irq timeout: status=0x50
hd2: unexpected_intr: status=0x58
[and so on]
at boot time and not get past that. If lucky, the system boots
up but still hangs (not responding to keyboard input) at seemingly
random moments.
Based on a hint from guillem, I tried passing -no-kvm-irqchip on
the kvm command line. And now it works great!
Known problem? Ideas for tracking it down?
Jonathan

I was installing the hurd using a Debian installation CD-ROM (see
<http://www.debian.org/ports/hurd/hurd-cd>) like so:
wget
http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/mini.iso
qemu-img create hurd-install.qemu 3G
kvm -m 512 -net nic,model=ne2k_pci -net user \
-hda hurd-install.qemu -cdrom mini.iso -boot d
Puzzlingly, the result would hang (and not respond to keyboard
input) at seemingly random moments. Sometimes right after "Enabling
FXSR" during bootup, sometimes after the text "auth" was printed,
sometimes later.
When it hangs, it is fairly easy to nudge it back into working again:
1. Hit ctrl-alt-2 to get a console.
2. Run "info registers"
I doubt the details matter --- it is just that some nudging got it
working again. By doing so and occasionally rebooting, I eventually
got a working installation.
Even after that, though, I was not able to boot hurd, instead
receiving the message described above.
