Thanx! I built a SMP kernel earlier today (in order to enable hyperthreading), and discovered that the lost interrupt problem appears to have gone away. In addition, dmesg no longer shows any "unexpected IO-APIC" messages. The only configuration changes from the previous kernel are: CONFIG_SMP=y CONFIG_ACPI=y CONFIG_ACPI_BUSMGR=y CONFIG_ACPI_CPU=y I guess that the next step is to disable hyperthreading in the BIOS, and see if the UP kernel still has problems. - 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/
