It's worth noting that most PCs today with ATX power supplies really only go into a "Soft Off" state, which is probably why the anomaly persists across a power off. You should also test if powering off and removing the power plug will allow booting to XP to work.Is this the correct summary of the problemXP boot: No good if before 2.6.13 runs on the hardware
scenarios.
Assume each one starts from cold boot (power off).
* 2.6.13(skge) boot => Good
* 2.6.13(sk98lin) boot => Good
* 2.6.13 + SK version of sk98lin => Good
* XP boot => Good
and do the normal shuttdown or reboot or power off.
The same for all linux kernel before 2.6.13 (tested
2.6.12, 2.6.11)
