I might be missing something here but it looks fine, > could you elaborate? Daniel is comparing 2.4.20-ac2 with 2.4.21-rc6. In 2.4.20-ac2, APIC routing is disabled by default and his kernel works. In 2.4.21-rc6, APIC routing is enabled by default and interrupts are not properly routed to his SCSI controller. If he boots with noapic, everything works fine. You'll have to ask Daniel for more details on his system if you want to figure out why interrupts are not being delivered. All I know is, from the output and his testing, it is pretty obvious that interrupts are not being delivered. -- Justin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
