I first got the kernel (and assorted utilities) from RedHat's roswell2, 
which had ext3 support compiled as a module. Now I upgraded to RedHat's 
2.4.9-6 kernel for RedHat 7.1 which also has support ext3 compiled as a 
module.


I looked into my fstab and I finally got rid of the problem. I had the 
following two entries

/dev/zip                /mnt/zip                auto 
noexec,nodev,nosuid,rw,uid=99,gid=99,umask=000,user,noauto 1 2
/dev/zip                /mnt/zip-mac            hfs 
noexec,nodev,nosuid,ro,uid=99,gid=99,umask=000,user,noauto 1 2

which I now have changed to

/dev/zip                /mnt/zip                auto 
noexec,nodev,nosuid,rw,uid=99,gid=99,umask=000,user,noauto 0 0
/dev/zip                /mnt/zip-mac            hfs 
noexec,nodev,nosuid,ro,uid=99,gid=99,umask=000,user,noauto 0 0

And the problem went away. It looks like fsck in rc.sysinit was trying to 
do something with these entries (even though they are marked noauto). The 
zero in fs_passno makes fsck completely skip it. I have util-linux 
2.11f-11.7.1 (RedHat's) and e2fsprogs 1.23-1.7.1 (RedHat's too).

However, I still don't see why block-major-20 was being probed (maybe it 
has nothing to do with ext3, and it was that I needed to updated the 
initscripts, but they do "fsck -T -a /" when the problem occurs and I 
don't see why that would need probing)

Cheers,
