| |
Hi, I've just stated, that the machine, in which I've experienced the problem boots correctly also without "acpi=off", when I switch off HyperThreading (HT) in BIOS. As kernel works correctly on machine with "true SMP" (Intel Core2 Duo), it seems that the problem must be related to HT specific part of kernel:
