[openfabrics-ewg] Re: NOP problem in ib_mthca on OFED RC4

[Michael S. Tsirkin]

Quoting r. Don.Albert at Bull.com <Don.Albert at Bull.com>:
> When I had the problem previously, Roland Drier suggested trying to load the ib_mthca module with "fw_cmd_doorbell=0",  which did avoid the error then,  and in fact does on this new problem.   But the question is why?    Updating the firmware on the old board seemed to have solved the problem before, but now it has occurred again on a fairly new card with recent firmware.    Has anyone else seen this problem?

Which FW revision do you have?
