Quoting Borja Marcos <bor...@sarenet.es> (from Thu, 11 Mar 2010

Of course CPUs have bugs, I don't doubt it. I was just wondering how
I coud reproduce the problem with a different hardware :) That's why
I said it was unlikely.
Besides, such a low level fault should produce many more problems
than such a well defined failure mode, as far as I know.
In my case I had a 7.1 system which was running fine. After updating
to 7.2 I got deadlocks after some minutes with UFS. Switching to ZFS
for the main data partition extended the lifetime to 3-4 hours. After
updating ZFS in 7-stable with the code from 8-stable this was extended
to 6 hours (periodic daily triggered the problem faster), and after
switching to exclusive locks instead of shared locks in ZFS the system
survived a night with several jails running periodic daily (but I had
to reboot in the morning because apache was not able to serve data
anymore). Everything else was working correctly. I would say this was
a very narrow problem case.
Bye,
Alexander.
