IO-APIC changes maybe? Guess I > better hack up a 2.1.89-4 kernel to compile for UP and start hammering > it...) yes, it could well be the IO-APIC changes. It must be related to your hardware configuration as i have a BM-DMA setup as well, but no problems. A few suggestions to find out what the differece is: - could you try testing with a _single_ disk? - testing UP mode is a good idea as well... - turn off DMA with hdparm -d0 /dev/hd[ac] - turn off IO-APIC irqs for the IDE driver, just add this to io_apic.c, right after setup_IO_APIC_irqs(): setup_IO_APIC_irqs(); make_8259A_irq(14); make_8259A_irq(15); ... but it's also true that systems with the IO-APIC code get used much harder, it could tickle otherwise inactive hardware bugs. (but this was not the case until your report, so i'd really first suspect some ide*.c incompatibility wrt the IO-APIC changes) -- mingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu | ||||||||||||
