Yes, apologies for taking so long with this. I tried the acpi_skip_timer_override boot option last night, after Tony pointed it out, and this also works around the problem. To summarize the cause is the changes made to early-quirks.c in the mentioned commit and when this is reverted the problem goes away. There doesn't seem to be any sign of a living HPET on this board or any way of enabling it in the current BIOS revision but it seems on intermittent boots the check in early-quirks.c returns, the timer override doesn't happen, and the kernel fails to boot properly. Btw, this is the Asus A8N-VM *CSM* main board, the non-CSM variety actually has a nForce 410 rather than an nForce 430 chip. I don't know whether they behave any differently but the two boards actually have different BIOS releases. If reverting the commit would disable the HPET on boards that do actually support it I personally don't mind using the acpi_skip_timer_override workaround. - Andrew - 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/
