I was trying to get my grsecurity patched vannilla kernel up and running in a dual opteron workstation, but it fails to mount all other partitions besides the root partition, which is passed explicitly in the grub config file. This happens because there is no udevd running like I would expect it to be, so when I look at /dev there are no sda1 and sdb1.

Why does this happen? When I run the default kernel everything is loaded as it should be.

I am not using any kind of initrd or modules.

Suse version is: 9.2 (64bits)
udev version is: 30 < -- this is kind of old, my gentoos are all on 70

I was running grsecurity on 9.2 (64-bit) without any problems.
RSBAC works well on suse 9.3 (64-bit) and worked earlier on 9.2 (although compiling admin-tools on suse is not straightforward)

It looks like you may have messed up config

udev version is old, but you are using old suse version
