When running 2.4.0-test9 on my Thinkpad T20 the HDD LED usually stays on all
the time. It seems random, some boots the LED will operate normally, but
most boots the LED will go on continually.
The system otherwise operates normally (all the data is correctly read and
written on the hard disk).
I have an IDE hard disk using DMA. I have attached the kernel config I am
using (no patches were applied to the kernel source).
2.4.x kernels work perfectly on the same machine.

Is the HDD led separate from the floppy LED? On my thinkpad, they're
one of the same.
If yes, I'd guess that you've built a kernel without floppy support
built in. The kernel used to turn the floppy motor off itself even
without floppy support, but this has been removed. IIRC it is now
the responsibility of the boot loader to do this.

You are so smart! I never even looked at the side to see whether the floppy
disk access light was on.
The floppy disk access light (that's part of the floppy drive) was on as well
as the system disk access light (I almost never use the floppy drive).

You are correct. "modprobe floppy" restored the operation of the disk access
light to normal.

Hmm. LILO bug then I guess.
