Hi Alan, its the Intel ICH4 chipset, I've tried it on 2.4.21-pre5-ac3 too,
to make sure its not something funny in the 2.4.21-pre5-gss kernel, same
problem occurred.

I've attached the lspci -vv output, and the /proc/ide/hda/settings file.

> No, you should get the same results.
On further investigation, I do get valid results on /dev/hdb, but i can't
get /dev/hda (the WDC WD800JB-00CRA1) to give me sane test results. i've di=
sabled
S.M.A.R.T. in the BIOS, done a cold boot, and not poked at the drive at all
with smartctl before running hdparm, and i still get the invalid results:

/dev/hda:
 Timing buffer-cache reads:   -3008 MB in  0.00 seconds =3D  -inf kB/sec
 Timing buffered disk reads:  -1504 MB in  0.00 seconds =3D  -inf kB/sec
Hmm.. suspicious results: probably not enough free memory for a proper test.

/dev/hdb:
 Timing buffer-cache reads:   128 MB in  0.27 seconds =3D474.07 MB/sec
 Timing buffered disk reads:  64 MB in  1.40 seconds =3D 45.71 MB/sec

I can't feel a noticable difference in speed for hda though.
