Re: [coLinux-users] Vista SP1 - complete failure

[Henry N. <hen...@ar...>]

Thanks. As I suggest last mail :-),
You have a buggy timer chip, found in Gparted log:

"""
..MP-BIOS bug: 8254 timer not connected to IO-APIC
...trying to set up timer (IRQ0) through the 8259A ...  failed.
"""

Some more I see: Why the BogoMIPS under coLinux are faster as in native.
Typicaly it is reverse.

Your Debian in coLinux:
Calibrating delay loop... 15151.92 BogoMIPS (lpj=75759616)

Your Gparted native live cd:
Calibrating delay using timer specific routine.. 3993.27 BogoMIPS
(lpj=7986550)

Try to boot with manualy set of the delay, run coLinux with additional
kernel parameter:
lpj=1234567
