Please narrow down kernel version if you want your problem to be cared.

Try 2.4.19, 2.4.20. There are also intermediate prepatches at

dmesg output and .config can also be useful.

Something very strange is going on with my machine. With 2.4.18, I was
getting 38MB/s on my main system disk (IBM Deskstar 60gxp), and 35 for
the other drives (Western Digital). The IBM drive is on a Promise IDE
controller (ASUS A7V266-E motherboard), and the others are on a PROMISE
2069 UDMA133 controller. However, with 2.4.21 and 2.4.22, it will not
set the using_dma flag for my IBM drive, but sets it for the others,
which now get sustained transfer rates of 46MB/s or greater. I'm using
the same options for all 3 kernels (at least, for the ATA/IDE options).
Any help would be appreciated, and I'll see if maybe I could do
something with it when I get time.

Ok, I tried 2.4.19, which I thought was pretty bad because it randomly crashed all the time, and it worked just fine with all my drives. 2.4.20 with the wolk-4.0 patch also worked. So, I'm guessing it was between 2.4.20 and 2.4.21....I could try all the prepatches as well, and narrow down exact prepatch, will take some time. dmesg output for 2.4.21 follows (uses a patchset for XFS, sensors, etc), along with my config, both compressed.
