problems with xfs as root fs

[Michael Wahlbrink <x_miw@xxxxxxxxxxxxxxxx>]

hi,
on my 'new' linux-box i've set up an linuxfromscatch system with xfs as 
root fs on an promise ide raid controller (using /dev/ataraid/dXpY). I 
use the kernel 2.4.18 with the xfs 1.1 patch.
Often after a (obviously clean) shutdown I have problems with booting 
into my system. I get a kernel panic saying thast there is something 
wrong with the log of the xfs filesystem. Than I must reboot with my old 
SCSI disk and run xfs_repair (often with the -L option ;-( ) to get the 
system running again.
Some hints what's wrong there? And how to get a working xfs-system 
without emergency partition ?

regards
micha
