Greetings,
Somewhere between 2.6.2-rc3 and 2.6.2, more specificly between 2.6.2-rc3 and
2.6.2-rc3-mm1 appeared a patch in the bitkeeper, that was included in
linux.patch used in 2.6.2-rc3-mm1, in 2.6.2 and it's still present.
The patch follows:

This patch should be -R's ASAP, since it cause major problems: as an example, I
have an Asus M3700N laptopwhere this patch causes the system to do this:

If I revert the patch lilo runs normally.

Please send us your /proc/partitions with, and without that patch.
If you disable nbd in config, does it help?
Are you using devfs?

With nbd disabled the patch causes no problems.

I don't know what LILO's problem is, frankly. My version is OK with it,
and my /proc/partitions is doing the same as yours.
vmm:/home/akpm> lilo -V
LILO version 21.4-4
Still, we probably want to suppress all those NDB majors in
/proc/partitions. I'll discuss it with the blocky guys.

Well, I'm using version 22.5.8 (the last version)... Maybe you could update
LILO and see if that's what causes the problem?
