Hello Brett,
A DMA related bug was fixed in FW ver *.0095 that was causing
the FW to stop responding.
Please upgrade the FW version to >= *.0095 and let me know if
you still see the issue.
Regards,
Sumant

Subject: Re: megaraid_sas waiting for command and then offline
The machines are Dell 2900s, so the mobo is custom. From a Dell SE,
"Dell uses a custom mobo that is Dell branded with the Intel chipset
Greencreek.".

I have the same or a similar issue running 2.6.17 SMP x86_64 - the
megaraid_sas driver hangs waiting for commands and then the
filesystem
unmounts, leaving the machine in an unusable state until there is a
hard
reboot (the machine is responsive but any access, shell or
otherwise, is
impossible without the filesystem). While I do not have much
debugging
information available, this happens to me about once every 6-7 days
in
my pool of seven machines, so I can probably get debugging info.
Since
the disk is offline and I can't get remote console, I don't have any
details except something similar to Dave Lloyd's post, below.
The only thing that the machines with these failures seem to have in
common is the fact that they are almost exclusively writes - they
are
slave database machines with large memory and pretty much just
replicate. The read/write machines seem to have less failures.
I am happy to help provide debugging information in any reasonable
way.
In the mean time, if there are any known suggestions or workarounds
for
the problem, I would be grateful for the guidance.
Here are what details on the controller. If you want additional
info,
let me know exactly what you need and I will do what I can to get it
to
you.:

Which motherboard are you using? We believe that this may be a
motherboard specific issue. It appears to happen on a SuperMicro
motherboard but not a Tyan motherboard.
