After upgrading from RELENG_6_2 to 7.0-RC1 I am experiencing system
becoming unresponsive during intensive disk operations. Only solution is
a power off. These hangs occured pretty much within a few hours of first
running 7.0-RC1. 6.2R was fine. I am not running ZFS.
The hangs are easy to reproduce by an unrar of an archive ~4.4GB. The
system will not hang during "normal" operations.
Below are the errors I get, output from dmesg, atacontrol cap and
smartctl tests. (The long test is aborted below, but as indicated
previously completed without errors)
These are the errors:
