Re: mfii hanging on boot

[cirr%sdf.org@localhost]

Hello Masa -

I was able to apply your patch to the 9.2 tree and built a kernel and
pxebooted it.  Unfortunately the status now looks like this:

mfii0 at pci5 dev 0 function 0mfii0: firmware fault

https://sdf.org/eu   (full boot sequence)

The machine is 8412km away in a data center and I don't have direct
access to it so I cannot unplug the battery, move the board to another
slot, et cetera.

I can, however, power cycle/reset the machine and access the MegaCLI to
look at the two raids.  Both appear to be intact and the controller
reports no errors, no bad disks or any other issues.

I'm hessitant to make any changes physically to the machine until I'm
absolutely sure that this is a recovery situation.

Thank you for your help on this, I appreciate it!

Stephen
