Unfortunately not. There were big changes to Linux's time handling between
2.6.16 and 2.6.18 so bugs may hav ebeen introduced while porting out own
timer code. It might be worth diffing the file time-xen.c from working and
non-working Linux kernels. It's weird that the failure mode is bad on the
T60p yet noone else has reported this bug, nor has our testing reproduced
it. :-(
