According to your system description it seems that you have a Targa Visionary laptop with a VIA chipset and a Mobile Athlon64. If so, then you probably have the same problem I reported some time ago: see <http://marc.info/?l=linux-kernel&m=117681226421346&w=2> and the followup messages. The conclusion was that the chipset's ACPI PM timer slows down when the CPU is in C2. The workaround is to boot with processor.max_cstate=1. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
