jffs2_gcd_mtd1 errors after reboot

Hi again,
Question about these errors I saw after a reboot on one of our development
embedded systems. The Kernel Virtual Memory errors are at the bottom.
Normally these units boot with no problems. The only thing I did different
prior to reboot was sync the system time, then write to the hwclock (which
has been done before without this problem). The unit then completely locked
and I had to power cycle it to reboot. On the next boot everything was
fine. I didn't see any JFFS2 errors on next boot either. I tried to
duplicate it with the same steps, and it boots normally. Any ideas on what
may have caused this?
Thanks in advance,
-Brian
