HPT374 performs badly in 2.5.67
My disks connected to a hpt374 controller are a lot slower in linux 2.5.67 than 2.4.21-pre5. Under 2.4 I get ~40 MB/s (as expected), but with 2.5.67 the rates drop to ~30 MB/s.
The system is an Alpha SX164. Disks are one Western Digital WD880BB, and one Seagate Barracuda V 120GB.
Is there any explanation, or (better) fix, for this degradation?
