Not quite -STABLE, but still interesting I hope: we run a PowerEdge 2550
with 4.4-RC4. Not under heavy load yet, and (thus ? ;-) no production
problems yet. But read on.

It was recognized without problems :

aac0: <Dell PERC 3/Di> mem 0xf0000000-0xf7ffffff irq 2 at device 2.1 on pci2
aac0: i960RX 100MHz, 126MB total memory, optional battery present (3)
aac0: Kernel 2.5-0, S/N fafaf001379810d2
aacd0: <RAID 5> on aac0

When we unplug a drive, the system nicely starts complaining.  But when
we reinsert the drive the whole thing (=filesystem access) hangs :( We
found out that we needed to reboot the system before reinserting the
drive. Raid rebuilding then works correctly.

You might want to check how this works for you.
