PATCH 1/1 Lost interrupt with HPT372A patch

Hi, I have a HighPoint RocketRAID 133 host adapter with HPT372A chipset. (firmware revision is 2.31)

When booting with 2.4.19-pre5-ac3, I get "hde lost interrupt". My HD drive is

hde: ST380021A, ATA DISK drive
hde: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=155061/16/63

The patch below turned out the problem.
