- 2.6.37-trunk-amd64 from experimental has the same problem[1].
- 2.6.32-5-amd64 from squeeze works fine.

I'll try bisecting.

Thanks,

[1] kvm command line:

        kvm -m 768 -net nic,model=ne2k_pci -net user hurd-installed.qemu

Result:

        start ext2fs: Hurd server bootstrap: ext2fs[device:hd0s1] exec
[waits a long time, I hit ctrl+alt, "info registers", etc in the
hope of waking it up", and then]
        kb_setleds1: unexpected state (1)
[a bunch of times]
        hd0: irq timeout: status=0x58hd0: unexpected_intr: status=0x58 { 
DriveReady Seek
        Complete DataRequest }
         { DriveReady SeekComplete DataRequest }

and it hangs again.  Adding -no-kvm-irqchip to the kvm command line
fixes it.
