Help with GIANT-LOCKED in REL5.3

[Chiang Seng Chang]

Hi,

Anyone knows if GIANT-LOCKED is something new in 5.3 ?

I have on the same machine running 5.2 which does not have any 
giant-locked in dmesg.

The only difference is that I changed the bios to boot 5.3 from the 
3ware raid drive. (oh, and I disabled a lot unused drivers in the 5.3 
kernel config.)

Thanks.
