I've had the same problem. Lockups with 2.4.14pre1 + ext3-patch, sysrq not possible, HD led is on. This is a 7IXE4 (AMD756), Duron 650, 384MB. 2 HD's, 1 CDROM. I've noted that on startup I got "spurious 8259A interrupt: IRQ7", and the machine locked hard on IDE activity (sometimes). after observing the above message and others like hda: timeout waiting for DMA ide_dmaproc: chipset supported ide_dma timeoutfunc only: 14 hda: read_intr: status=0x51 hda: read_intr: status=0x04 hda: read_intr: status=0x51 hda: read_intr: status=0x04 hda: read_intr: status=0x51 hda: read_intr: status=0x04 ide0: reset: success The I've tested disabling some options. So far my best result was disabling APIC on UP (both - IOAPIC and APIC) - so far I've had no more lockups. Will test further, but this seemed to be the problem for me.
