I've used kernel 2.6.32 based on P2020RDB_20100429-ltib or  P1020_P2020RDB_20101101_ltib for P2020 or P1011


When PCIE device is stuck,I expect that P1011 handles it as just like request timeout and escapes pcie operation.


Contrary to expectations, P1011 just wait that operation completes which is not completed.

Additionally, timer interrupt can work well and watchdog can be triggered.

That is, even if cpu is alive, cpu don't work anything..


In order to avoid that situation, EDAC driver of recent kernel seems to be useful.


But kernel 2.6.32 is old-fashioned.

EDAC driver of recent kernel is not suitable to it.


Can you have a solution for it? a kind of patch ?
