I've confirmed this problem with several 10.04 LTS (amd64) machines VM's
running on a VMware vSphere system. Each machine that had an uptime of
211 days suffered a sudden softlockup, triggered by an innocent-looking
'apt-get install libyaml-perl'. The machines were running
2.6.32-30-server.

Some consoles showed the "stuck for 17163091968s" message, others just
these "stuck for 61s" and "task ... blocked for more than 120 seconds".
I've also seen a variant with the value 17163091988s.

Other machines that were quite identical, but running either a bit older
kernel (2.6.32-26-server, uptime 365 days) or a newer one
(2.6.32-33-server or newer, uptime less than 115 days) were not affected
by this issue.

Is there a way to reproduce the error? Maybe a way to set the
problematic clock value to somewhere near the 210 day limit?
