It is RHEL5.6 kernel which the known bugs have been fixed. I guess that RHEL6.0
kernel also has this bug (since this bug is in Ubuntu 10.04 kernels).
So, I want to try establishing the steps to reproduce.
Does anybody come up with common characteristics between below hangups?
(a) Updating rpm packages using rpm executed from zypper.
Although, the process actually hanged is /bin/sh which
I guess was invoked for pre- or post- install scripts.
Installing: grub-0.97-173.6 [91%]
(b) Logging in from console using /bin/login .
Although, the process actually hanged seems to be auditd process
which attempted to write an audit log immediately after login event.
(c) PostgreSQL and Apache.

Writing with O_SYNC? Or calling fsync()? Or calling ftruncate()? Or ...?
