SCSI\JRAID is a reference to a storage device connected to the
Jmicron JMB363. A pseudo-SCSI software interface is used, for
devices other than some of the Southbridge ports.

The Harddisk6 on the other hand, could be a disk on the Southbridge,
such as a SATA interface. (I still haven't found a reference, that
explains the letter "D". It won't be the D: drive, if that is what
you're thinking.)
It sounds like something caused the machine to freeze, such that
some disk I/O timed out without completing. So the error messages
are a side effect of whatever happened. It is even possible, that
in the middle of doing some I/O, that the kernel sat there
waiting for some operation to complete, which means other
important activities timed out in the intervening period.
(The kernel is not supposed to do that, by the way.)
If you're jammed up for five seconds, that might be
enough for some disk I/O to fail and get logged. And
the logging can only work, if it becomes unstuck again.
