hello, I have a server running 5.4-STABLE for months with a compaq smart array raid controller. I recently discovered that kernel was reporting errors from this device : Sep 11 18:16:47 marge kernel: ida0: ida_timeout() qactive 1 Sep 11 18:16:47 marge kernel: ida0: IDA_INTERRUPTS Sep 11 18:16:47 marge kernel: ida0: R_CMD_FIFO: 00000000 Sep 11 18:16:47 marge kernel: R_DONE_FIFO: 00000000 Sep 11 18:16:47 marge kernel: R_INT_MASK: 00000000 Sep 11 18:16:47 marge kernel: R_STATUS: 00000000 Sep 11 18:16:47 marge kernel: R_INT_PENDING: 00000000 Sep 11 18:16:56 marge kernel: ida0: ida_timeout() qactive 1 Sep 11 18:16:56 marge kernel: ida0: IDA_INTERRUPTS Sep 11 18:16:56 marge kernel: ida0: R_CMD_FIFO: 00000000 Sep 11 18:16:56 marge kernel: R_DONE_FIFO: 00000000 Sep 11 18:16:56 marge kernel: R_INT_MASK: 00000000 Sep 11 18:16:56 marge kernel: R_STATUS: 00000000 Sep 11 18:16:56 marge kernel: R_INT_PENDING: 00000000 Sep 11 18:17:01 marge kernel: ida0: ida_timeout() qactive 1 Sep 11 18:17:01 marge kernel: ida0: IDA_INTERRUPTS Sep 11 18:17:01 marge kernel: ida0: R_CMD_FIFO: 00000000 Sep 11 18:17:01 marge kernel: R_DONE_FIFO: 00000000 Sep 11 18:17:01 marge kernel: R_INT_MASK: 00000000 Sep 11 18:17:01 marge kernel: R_STATUS: 00000000 Sep 11 18:17:01 marge kernel: R_INT_PENDING: 00000000 theses messages are more and more often reported. the system doesn't seem to be affected (no disfunction, no performance loss). my questions are : - what does this mean ? - is it a serious problem ? - can it be related to a dump process running for long time that is unkillable ? (i mean that kill -9 is ineffective) - if it is serious, what can i do ? relax and enjoy ? thanks for your help ! PS: i posted another question to acpi@ [1] about to the big noisy fan that doesnt slow down as it does with windows. it is still unanswered so if anyone has an idea, i'd be very pleased !
