[Qemu-devel] -kernel-kqemu troubles with linux 2.6.16.5 (kanotix easter) guest

[Juergen Lock]

Hi!

 The latest
    http://debian.tu-bs.de/project/kanotix/preview/KANOTIX-2006-Easter-RC2.iso
hangs on boot with -kernel-kqemu after printing 
    serio: i8042 KBD port at 0x60,0x64 irq 1
(selected text mode in grub with f4 and removed `quiet' from boot line).
dmesg of a successful boot (with `regular' kqemu) below, the only
difference I see with the hanging -kernel-kqemu is an added line
    Machine check exception polling timer started
before
    Total HugeTLB memory allocated, 0

 top shows the box 95% idle, an attached gdb finds it at
    4527        ret = select(nfds + 1, &rfds, &wfds, NULL, &tv);
in vl.c
