Subjectmb/s oddness between linus kernel & ac
Date
[sorry if this was sent twice]

Hi, I recently tried out both kernels to see the difference between
hdparm -t tests, and the results are disturbing.
Both kernels are configured the same, heres the results:

Linus kernel 2.4.14pre4:
/dev/hda:
Timing buffered disk reads: 64 MB in 1.59 seconds = 40.25 MB/sec
AC kernel 2.4.13ac5:
/dev/hda:
Timing buffered disk reads: 64 MB in 2.47 seconds = 25.91 MB/sec

I checked that both had the same settings [with hdparm -v /dev/hda]
The hdd is a seagate 60gig 7200rpm ide, & chipset is via kt133a
If more hardware info is needed, let me know.
