kernel error message from device ida

[oHmEr]

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 !
