[Linux-aus] Hardware problems

[Ben Donohue]

Thanks Adam,

dmesg shows the following...

elite3 elite3 # dmesg  | grep -i raid
[    1.241678] megaraid_sas 0000:03:00.0: FW now in Ready state

So i presume the following line

[    1.264418] megaraid_sas 0000:03:00.0: Failed to init firmware

is the one that is causing the problem.

I'll take your advice and get onto the Dell linux list and see what they 
have to say.

I've spent days on trying various things. Could be a firmware issue.

Sometimes these things need windows installed to upgrade the firmware... 
sigh...

Thanks for your and everyones help.

Ben
