boot process stops at "ENABLING IO-APIC IRQs"

Hi there!

I've got some strange problem with my quite new laptop (hp pavilion dv9040ea).
Sometimes when I try to boot my archlinux the boot process suddenly hangs up. This is the output at which the boot process stops:

CPU: L2 Cache: 512K (64 bytes/line)
CPU0(2) -> Core 0
Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#0.
Compat vDSO mapped to ffffe000.
Checking 'hlt' instruction... OK.
SMP alternatives: switching to UP code
Early unpacking initramfs... done
ACPI: Core revision 20070126
ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not found.
CPU0: AMD Turion(tm) 64 X2 Mobile Technology TL-56 stepping 02
SMP alternatives: switching to SMP code
Booting processor 1/1 eip 3000
Initializing CPU#1
Calibrating delay using timer specific routine.. 3617.17 BogoMIPS (lpj=6027476)
CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
CPU: L2 Cache: 512K (64 bytes/line)
CPU 1(2) -> Core 1
Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#1
CPU1: AMD Turion(tm) 64 X2 Mobile Technology TL-56 stepping 02
Total of 2 processors activated (7238.03 BogoMIPS).
ENABLING IO-APIC IRQs
..TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1
_

This last sign is the blinking cursor. But from there on there is no possibility to write anything or do anything else than a manual shutdown with the off-button.

This problem occurs only randomly. Until some weeks ago it appeared only about one time on 20 boots, but now it comes even 6 times in a row until my laptop is able to boot properly. Has anyone an idea what the problem is and how I may solve it?

Greetings,
yaku

Re: boot process stops at "ENABLING IO-APIC IRQs"

You could try booting with noapic appended to the kernel command-line but that will probably cause more issues than just random boot issues. This is a known and rather unsolved issue with newer HP laptops.

Ok, thanks.. I think I will have to leave it as it is.
