Public bug reported: I've had this problem for a long time now, on 8.04, 8.10, 9.04, and now 9.10, and it hasn't been solved. As you can see by my output, I have a quad-core AMD processor. However, most of the time it fails to boot. I've turned off the quiet kernel option, so I can see what happens, and if it tries to boot more that one core (but less than all four) it fails to boot. I get a "not responding" message when booting, and after I get the kernel message along the lines of "booting x cores (yyyyy.y BogoMIPS)" the boot hangs (where 1 < x < 4). I will try to capture the exact output, but since I don't have access to a shell when this happens, I can't easily grab it.
The data collected on this machine for this ticket was created on a clean, one-core boot. I enabled these options to the kernel: noapic nolapic acpi=noirq pci=noirq, but that disabled SMP (and hence, I was able to boot). When I upgraded this system from Jaunty to Karmic, it booted all four cores fine, so I know it can work. I'm pretty sure it's a hardware bug, due to the fact that this motherboard manufacturer doesn't explicitly advertise that this motherboard supports this processor. My own fault for not paying close attention to that. I'm looking for a workaround, perhaps the kernel boot line magic to get this working every time. Thanks in advance!
