Public bug reported:
I received a brand new workstation (Dell Optiplex 960 with dual 360 gig
HDs running on an onboard RAID controller) and installed Jaunty x64 on
it last week using the alternate CD. Since that time I have experienced
random freezes of my machine. It appears to be an issue with the built-
in isw RAID. The machine doesn't totally lock up (I can move the mouse,
access menus, etc.), but anything related to hard drive activity
completely stops. I have noticed this in Firefox, Thunderbird, and
Eclipse. Compiz will grey the windows indicating they are not
responding and they will not take keystrokes. Typing "ls" at a command
prompt will just sit there. After a period of time (usually several
minutes) the machine will resume as if nothing happened. I checked my
log files and cannot find anything logged when this happens.
It is not an issue of memory, the machine has 8 gig on board and only
about a third in use most of the time. I have not found a consistent
pattern to cause the issue.
