2.6.12 (SGI-XFS CVS-2005-06-14_05:00_UTC with ACLs, no debug enabled) is
fine. I returned back to this kernel because I had another incident on my
/home partition. 2.6.13 from SGI CVS seems to be dangerous for me.

Do you realy think that memory break on two different machines just after
switch to 2.6.13 kernel? But ok I will do it this night.

The kernel is SGI-XFS CVS-2005-09-07_05:00_UTC. Partition /dev/hda10 is
mounted with ihashsize=64433,noikeep,logbufs=8. /home with
noikeep,logbufs=8. I attached kernel config but it is similiar to
2.6.12 working config.

One more notice: I tried to use CONFIG_KEXEC on x86_64 and kernel could not
recognize XFS superblock. I didn't try it on i386.
