SubjectRe: 2.6.37-rc3-git installed modules zero bytes long - only on root xfs
The problem occurs on the systems with root on xfs, the boxes with ext4 
have not been affected.
On the 2 affected boxes, 2.6.36-rc6-git6 - one had no problems and and
one several rebuilds and reinstalls of modules had to be done to get it
to work with the exception of one module.
slipstream:/home/lancelot # depmod -ae -F /boot/System.map
WARNING: Can't read module
/lib/modules/2.6.38-rc6-git6-smp/kernel/drivers/mtd/nftl.ko: Not a directory

Listing the module it says 0 bytes whereas before the reboot it was OK.
