"The Linux admins who experienced the crashes started a
thread to that effect on the slashdot.org community site. In
response, developer Linas Vepstas pulled together a summary of the
issue on the Kernel mailing list lkml.org.
"According to Vepstas, the 53 reported hard crashes at or near
midnight December 31 2008 had a few things in common. In all cases
the systems were not pingable and power-off cold reboots were
required to get them back to normal working conditions. There were
no syslog error messages, no kernel oopses and no core dumps."
