Asus Eee 1101HA hangs

I have just bought an Asus Eee 1101HA and (after compiling a custom kernel with the correct drivers) it is working almost perfectly. Sometimes the whole system just hung and after a keypress the hung had gone and it was OK for a while until the next hang…

This had been happening in console and under X too. I thought it might be a kernel-related issue, some kind of a timer or interrupt problem, maybe timeout.

All in all this turned out to be an APIC problem, and the machine is working perfectly with a noapic boot parameter.
