I have an openSUSE 10.2 on an HP pavilion DV9363 laptop. Since half a year I have sometimes problems when booting. It will freeze, mostly with as last message “Activating device mapper …” Starting in failsafe mode always works and revealed the following differences between a good and a bad start.
Bad start:
<6>PCI: Using IRQ router PIIX/ICH [8086/27b9] at 0000:00:1f.0
<6>PCI->APIC IRQ transform: 0000:00:01.0[A] → IRQ 121
<6>PCI->APIC IRQ transform: 0000:00:1b.0[A] → IRQ 161
<6>PCI->APIC IRQ transform: 0000:00:1c.0[A] → IRQ 129
<6>PCI->APIC IRQ transform: 0000:00:1c.1** → IRQ 121
<6>PCI->APIC IRQ transform: 0000:00:1c.2[C] → IRQ 137
…
Later this will give:
<6>device-mapper: ioctl: 4.7.0-ioctl (2006-06-24) initialised: dm-devel@redhat.com
<3>irq 121: nobody cared (try booting with the “irqpoll” option)
<4>

In a good start I find in the boot.msg:
<6>PCI: Transparent bridge - 0000:00:1e.0

<7>ACPI: PCI Interrupt Routing Table _SB.PCI0.PEGP.PRT]

…
Booting with irqpoll does not solve the problem. I read that for the IBM Thinkpad there is a boot option nolapic. But does this also exist for other laptops?**
