Hi,

ok, i'm 100% stumped now... i've tried the following...

1. 2.4.12 + XFS (2001-10-11)  SMP - egcs
2. 2.4.12 + XFS (2001-10-11)  SMP - gcc 2.96
3. 2.4.12 + XFS (2001-10-11)  SMP - gcc 3.0.1
4. 2.4.12 + XFS (2001-10-11)  - egcs
5. 2.4.12 + XFS (2001-10-11)  - gcc 2.96
6. 2.4.12 + XFS (2001-10-11)  - gcc 3.0.1

all with the same result, total root fs corruption on rebooting (random number 
reboots), Keith Owens pointed out it could be the partition problem the kernel 
was
having & sent me a 2.4.12 => 2.4.13pre2+XFS patch, i applied it and tried the
following....

7. 2.4.13pre2 + XFS (?)  SMP - egcs
8. 2.4.13pre2 + XFS (?)  SMP - gcc 2.96
9. 2.4.13pre2 + XFS (?)  SMP - gcc 3.0.1
10. 2.4.13pre2 + XFS (?)  - egcs
11. 2.4.13pre2 + XFS (?)  - gcc 2.96
12. 2.4.13pre2 + XFS (?)  - gcc 3.0.1

still all to no avail, i've also tried using the 2.4.12 XFS patch on 2.4.13pre2
with a few modifications... still same result. ext2fs works fine aswell as
reiserfs, so i'm 100% certain the bug is in XFS. all the above 12 test cases
i preformed on multiple different servers, amd aswell as intel, diff 
motherboards
, different ram, different harddrives.


here is a list of software installed....
mount-2.11g
xfsdump-1.1.3
xfsprogs-1.3.7
quota-3.01
acl-1.1.3
attr-1.1.3
dmapi-0.2.2


there are 3 partitions on the harddrive apon install...
/dev/hda1  - 8Mb /boot  (XFS)
/dev/hda2  - 128Mb swap  (SWAP2)
/dev/hda3  - <whats left> /  (XFS)


fstab has the following entries...
/dev/hda1  /boot      xfs      defaults 2 0
/dev/hda2  none       swap     defaults 0 0
/dev/hda3  /          xfs      defaults 1 0
none       /proc      proc     defaults 0 0


i'm using devfs, with automount enabled... fstab wouldn't matter
cause nothing reads it before the error happens, 99% of the time
devfs won't even mount cause there is no more directory structure
on the hdd due to corruption.


any help whatsoever would be very greatly appreciated!
Nigel
