I'am seeing filesystem corruption with all current 2.6.22-rc4 kernels . 

To verify that I did the following steps:
First install a kernelsource rpm on a bugfree kernel to get a "good" reference
uname -a
Linux PC1 2.6.18.8-0.3-default #1 SMP Tue Apr 17 08:42:35 UTC 2007 x86_64
x86_64 x86_64 GNU/Linux

# rpm -i --force /home/mk/kernel-source-2.6.22_rc4_git3-20070612164740.
# rpm -q --verify kernel-source-2.6.22_rc4_git3-2007061216474

No corruption seen here
# cp -a /usr/src/linux-2.6.22-rc4-git3-20070612164740 /usr/src/linux-2.
# reboot
Now reinstall that kernel source when running the the "bad" kernel
# uname -a
linux PC1 2.6.22-rc4-20070608144231-default #1 SMP Sat Jun 9 17:12:30 C
# rpm -q --verify kernel-source-2.6.22_rc4_git3-20070612164740
#

# rpm -e kernel-source-2.6.22_rc4_git3-20070612164740
# rm -rf /usr/src/linux-2.6.22-rc4-git3-20070612164740
# rpm -i --force /home/mk/kernel-source-2.6.22_rc4_git3-20070612164740.

# rpm -q --verify kernel-source-2.6.22_rc4_git3-20070612164740

At that point there seems to be no corruption yet. But after rebooting  the
system and checking again there is filesystem corruption

'# rpm -q --verify kernel-source-2.6.22_rc4_git3-20070612164740
# sync
# reboot

# uname -a
linux PC1 2.6.22-rc4-20070608144231-default #1 SMP Sat Jun 9 17:12:30 C

# rpm -q --verify kernel-source-2.6.22_rc4_git3-20070612164740

And doing a diff with the saved "good" kernel source tree will give you the
attached  corruption.diff
# diff -urN linux-2.6.22-rc4-git3-20070612164740-good
linux-2.6.22-rc4-git3-20070612164740 |tee corruption.diff

There are no error messages in the system log files.
