Both old and new kernels have XT-PIC-XT in /proc/interrupts and both work. Notable differneces from dmesg. The TSC calibration one is interesting. 2.6.34 tells a failure for some reason. Re-testing 2.6.34 results in normal "Fast TSC calibration using PIT"... -nr_irqs_gsi: 16 +nr_irqs_gsi: 17 -Fast TSC calibration failed -TSC: PIT calibration matches PMTIMER. 1 loops -Detected 897.087 MHz processor. -Calibrating delay loop (skipped), value calculated using timer frequency.. 1794.17 BogoMIPS (lpj=3588348) +Fast TSC calibration using PIT +Detected 896.953 MHz processor. +Calibrating delay loop (skipped), value calculated using timer frequency.. 1793.90 BogoMIPS (lpj=3587812) +ERROR: Unable to locate IOAPIC for GSI 8 +ERROR: Unable to locate IOAPIC for GSI 13 +ERROR: Unable to locate IOAPIC for GSI 12 +ERROR: Unable to locate IOAPIC for GSI 1 +ERROR: Unable to locate IOAPIC for GSI 6 +ERROR: Unable to locate IOAPIC for GSI 4 +ERROR: Unable to locate IOAPIC for GSI 3 +ERROR: Unable to locate IOAPIC for GSI 7 -- Meelis Roos (mroos@linux.ee)
