   System locks up after running a short time.  Had it hang once

When the system hangs, the mouse movement is tracked across the screen  
and I can ping the node. There is no response to clicking on a mouse  
button or trying to type anything into a field. It also does not respond  
to ssh or to <CTRL><ALT><F1>.
    

Maybe it's a totally different issue, but I also noticed system lockups,
that started after I converted the system to Software-RAID1.  However, in
my case the lockups only occur after 3-10 days uptime.  One day I was able
to capture a couple of syslog entries:

| Jun 12 09:50:47 tardis kernel: hdg: lost interrupt
| Jun 12 09:50:47 tardis kernel: hdg: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
| Jun 12 09:50:47 tardis kernel: hdg: drive_cmd: error=0x04 { DriveStatusError }
| Jun 12 09:50:47 tardis kernel: ide: failed opcode was: 0xb0
| Jun 12 09:51:07 tardis kernel: hdg: dma_timer_expiry: dma status == 0x21
| (2 x WD2500SB-01RFA0 on a PDC20276 (MBFastTrak133))

The HDD LED is permanently on.
  

Wonder if hardware or software is happening, sounds like an mishandled 
hardware error, but I'm guessing. I have a server with RAID1 and Fedora 
2.6.22.14-72.fc6PAE kernel, up 72 days, no problems.
