IO-APIC bug: regular kernel, UP, no IO-APIC or APIC on UP enabled, compile
fails (does *everyone* run SMP or at least UP + APIC now?)
spinlock deadlock: run an smp kernel on a up machine. On mine here all I
have to do is try to boot to multiuser mode, it won't make it through the
startup scripts before it locks up by trying to reenter common_interrupt
on the only CPU. Seems like an SMP kernel on UP hardware doesn't disable
interrupts properly maybe? I get task lists via alt-sysreq when the
machine should be hardlocked I think. Anyway, this is what has been
tricking me into thinking I had an IDE problem. IDE is innocent, it's the
core interrupt handling code.
Back to work on scsi stuff now that I have a decently running 2.5.43
system, I'll let someone else deal with these.
