I'm having a lot of troubles after adding a third AOC-SAS2LP-MV8 card. Worked
quite nicely with two, but with the third card I get a lot of

These two disks is (and it's always different disks), strangely enough (?), on the
oldest card (which never shown any problems before - if it had been the newest, one
could have considered hardware problems).
And shortly after this, the kernel hard locks, forcing the hardware watchdog to reset
the machine.
This is, currently, kernel version 3.18-rc3 (I've tried so many versions the last couple
of months), but I notice that the mvsas driver haven't had any real changes since 3.9 or
there a bouts (one of the first that actually worked,w which I tried about a year or so
ago).
