,
I'm stuck with 2.4.16, because newer kernels oops while booting.
I'm using LVM for root partition, starting system with
initrd. On working kernels, normally "Mounted devfsd on /dev" appears.

try booting with devfs=nomount as devfs is not properly configured on
your system.

No, the problem is that he needs to apply the latest devfs patch. Some
of these problems have been fixed weeks ago. Grab devfs-patch-v199.7
and apply the appended patch as well. Let me know how it goes. I want
to release a new patch ASAP.

Richard....

what is this swapper process involved in 2.4.17 oops ? could it be
spawned when devfs thinks there is already a root fs mounted at boot
time before mounting the root fs given to the boot loader ?

It's blowing chunks even without devfs.
But you've pointed out something important. This is a heavily
upgraded RedHat 6.0 system and maybe there are some things which it
is doing which is inappropriate for the 2.4 kernels. I vaguely remember
a problem a while back with swapping and the swapper daemon and some
systems blowing chunks. All my various RedHat systems (6.0, 6.1, 6.2,
and 7.2) are all running kswapd. No "swapper" process, per se. And
init always has "1".
But even if some old application is doing something ill behaved,
that's still a problem since applications should not be capable of causing
such an oops. So that makes two problems, one in user space and one in
kernel space.
But... I've disabled swap on the afflicted system (it's got
enough memory that it damn well should have never swapped anyways). We
shall see what we shall see over the next couple of days.
Good point though...

17 == EEXIST
Your mkinitrd creates /dev/root in any form and devfs_do_symlink(root)
fails. We had the same pornlem in mandrake and Juan ended up commenting
it out in fs/super.c:
// devfs_mk_symlink (NULL, "root", DEVFS_FL_DEFAULT,
// name + 5, NULL, NULL);
