However, with the same setup, and with kqemu active, I was able to
install Kubuntu 6.06 amd64, without experiencing such a crash.
Still, two issues with that Kubuntu instance:
- grub segfaulted, failing to install the boot loader on the hard disk
image (I ended up using lilo instead);
this also happened previously when trying to install debian
testing amd64 *without using kqemu* (maybe some grub bug?);
- without or without the kernel option
clock=pit
I got, already at boot time:
Losing some ticks... checking if CPU frequency changed
[...]
warning: many lost ticks
Your time source seems to be instable or some driver is hogging
interupts
and now, about 1.5 hour after booting, the guest clock is about 1.5
hour ahead of the host clock (maybe because the host has been idle
and working at about 1/2 the full clock speed?) This clock shifting
did not occur with a Windows XP Pro guest, which usually remained
late by less than 1 minute.
Best regards
