Hi, I'm using Ubuntu dapper on my Macbook 2GHz, in dual boot with mac os x using rEFIt (no bootcamp).
I noticed that very often, the Macbook can't boot on my Linux kernel, stopping with a kernel panic : (I copy manually the interesting lines) " [...] Total of 2 processors activated (5825.50 BogoMIPS). ENABLING IO-APIC IRQs ..TIMER: vector=0x31 apic1=0 pin1=2 apic2=1 pin2=-1 ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up timer (IRQ0) through the 8259A ... failed. ...trying to set up timer as Virtual Wire IRQ... failed. ...trying to set up timer as ExtINT IRQ... failed :(. Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with apic=debug and send a report. Then try booting with the 'noapic' option " It can happen while cold booting, while rebooting from macosX, while rebooting from GNU/Linux. Booting with apic=debug doesn't change anything in the kernel output before the panic. I observed this problem with the ubuntu 2.6.15.26 and a manually compiled 2.6.17.8. Is someone having the same experience ? Thanks Pierre -- - Mélanger 3 parts d'essence pour 1 part d'acide sulfurique.
