Amancio Hasty:
|A cursory analysis of the interrupt status info that you send us seems to
|indicate that you are getting excessive PCI errors.
...
|Here is a sample output from my P100:
|Feb 22 05:51:20 cioloco /kernel: STATUS 0 d000206 30701c
|Feb 22 05:51:20 cioloco /kernel: STATUS 0 d000a04 3077a4
|Feb 22 05:51:20 cioloco /kernel: STATUS 0 d000a04 3077a4
|Feb 22 05:51:20 cioloco /kernel: STATUS 0 c000206 30601c
|Feb 22 05:51:20 cioloco /kernel: STATUS 0 c000206 30601c
...
| ^^^^^^^ BKTR_INT_STAT
|BKTR_INT_STAT is the second value in the output as you can see
|bit 15 is never set which means that the Bt848 is not having
|problems accessing the host memory.
A piece of my output:
STATUS 0 dc000206 100001c
STATUS 0 dc000a04 1000f24
STATUS 0 dd000206 2b901c
STATUS 0 dd000a04 2b9f24
Bit 15? Are some bytes swapped in the port mapping? It looks to my like
your low-order word (bits 15->0) is the same as mine. The differences look
like your bits 28,30, and 31 which are in the RISCS field.
I guess I might be missing something.
