Re: [problem] mpt2sas load fails with LSISAS2008

[Paul Johnson <pjay@xxxxxxxxxxx>]

There is a bug report here https://bugzilla.kernel.org/show_bug.cgi?id=92351

I found mpt2sas is loaded successfully up through 3.4.0 and fails in 
3.4.1; in 3.4.1 it will load
if pci=realloc=off is added to the command line.

A file with dmesg output for 3.4.0 3.4.1 and 3.4.1 with pci=realloc=off 
is attached to the bug report.
