I am running 2.4.2 as obtained from redhat, but I have experienced the same problems with a kernel compiled from the 2.4.2 sources at kernel.org. I am experiencing troubles with enabling MPS 1.4 and USB. I have an ABIT VP6 motherboard with two stock 733MHz PIIIs. If I set MPS1.1 in the bios then my IOmega Photoshow usb zip drive works, the usb interrupt appears on irq 9 and after a day or two I experience a hard (sysreq doesn't work) lock. It seems usb related since doing usb things i.e. mounting the drive sometimes cause the lock. If I set MPS1.4 in the bios then the usb interrupt appears on irq 19, whose count is alway zero, and the zip drive doesn't get registered. If give the noapic command line then things appear to work, irq=9,don't know about the hard locks, but booting seems much slower. Of course I can provide much more information but I wonder is this a common problem and what are the consequences of the noapic command? David
