Please note that only level-APICs seem to be affected. We don't see these high interrupt rates anymore when APIC is disabled in the BIOS. I also noted that the POST LED on the board flips between 94 and 96 which it does not under WinXP where FF is displayed. I have also a SATA Drive attached to the internal controller and under pre5 the box freezes if i do any serious amount of disk thoughput - for example using bonnie++. Maybe this is somehow related to this interrupt problem. I experience freezes with current 2.5 kernels too. WinXP is installed on the SATA Drive and rock stable, so this actually seems not to be a hardware problem per se. > vmtstat 2 > procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- > r b swpd free buff cache si so bi bo in cs us sy id wa > 0 0 0 680320 35816 278576 0 0 30 66 1995 313 38 4 58 0 > 0 0 0 680316 35816 278576 0 0 0 0 322131 7 0 0 100 0 > Is this normal? If it were i would be desperate to hear why for my most frequented nameserver (>300queries/s) hardly even does 1000 interrupts/s. ;) waves, Stefan - 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/
