(I'm not on the list, please CC me in your replies)
I have a HP DV6409nr Pavilion notebook that came preloaded with Windows Vista that Linux doesn't seem to want to boot properly on.
Currently, 'noapic noirqdebug' sort-of works for x86_64 kernels, but Vista seems to be able to use the APIC just fine. I've disassembled the BIOS to pull out the bios pirq and routing table and from what I can tell, it's pretty flexible -- Linux and Vista both set up the same IRQs when in APIC mode, save for the HPET. Vista sticks the HPET on IRQ 0 and 8, Linux sticks it on 2, 8, and 31. The two USB controllers get assigned IRQ 22 in both Vista and Linux, but under Linux a few seconds after accessing a USB device causes the system to lock up solid without an oops. Most of all I'm trying to get this laptop running in APIC mode so I can run Xen.
This system has no serial port, and USB seems to be problematic; can anyone suggest how to figure out what is causing the lock up? When the system freezes, it locks up so solid that sysrq doesn't work. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
