So, I've solved my problem, but haven't completely bottomed out on the cause. Not only has the problem vanished, but the system is noticeably quicker. Here's what I did: Got the 090997 kernel sources and rebuilt a kernel *without* the following options: > cpu "I686_CPU" > options "CPU_FASTER_5X86_FPU" and with the following *changed* options: > options NSWAPDEV=1 > options MAXCONS=4 > controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr > controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr So it could be the newer kernel, or any of these other changes. I am a bit suspicious about the "CPU_FASTER_5X86_FPU", but who knows. I'm going to put back the AUTO_EOI's, re-add the flags to wdc0, and wdc1, and hope for the best. That'll probably be where my investigation ends unless someone tells me they're keen. ;) Cheers, Andrew. -- In message "Help! keyboard lockups - could be kernel bug ?", Andrew Atrens writes: > > Terry wrote: > > > > Somone else was reporting serial port lockups when they were hitting > > their IDE drive hard. > > How well supported is the 430TX chipset?
