Still does not work in 2.6.3rc2 did you enable lapic? we have some problems with both acpi and lapic enabled. Sorry it took me so long to respond. Yes that worked. I can't adjust the cpu freq, but I suspect that may not be possible on my laptop. I can not get temprature and battery. If you have any clues on the cpu (Athlon XP) I would love to hear them. I meant to say, I CAN get the temperature and battery. so this problem goes away with "nolapic"? is "nolapic" still needed in 2.6.4? thanks, -Len That is correct. Using nolapic fixes the problem. is nolapic still required on 2.6.5? Created attachment 2681 [details]
test patch to not re-enable LAPIC if BIOS disabled it
please test this patch w/o any boot parameters and let me know
if 2.6.5 (or so) boots. There are several ways of enabling the LAPIC,
and this patch disable the technique where Linux enables the
LAPIC when the BIOS had it disabled. It might be that we always
want to do this when in ACPI mode.
*** This bug has been marked as a duplicate of 1269 *** Len, I applied the patch as suggested in your reply to me on the lkml (re: new laptop woes), my hp pavillion ze4430us/slackware box boots fine w/ the patch applied to either 2.6.5 or 2.6.6, although it still prints the ACPI: IRQ9 SCI: Level Trigger. message that it hung on, and your statements: LENB: !cpu_has_apic LENB: NOT reenabling LAPIC also printed, aside from that as far as I can tell, everything is working fine. BUT it definatly boots ;] thanks. |
