RHEL4 freeze

[Susan Baur]

Hi,

If this is a Dell PowerEdge box, there is a known issue with the RAID  
controller that causes the system to completely freeze up under high  
IO. See Dell's Linux-PowerEdge list archives at http:// 
lists.us.dell.com/pipermail/linux-poweredge . I've stopped getting  
the list, but I know that it was discussed back in Feb of this year.  
As I recall, the fix was to upgrade the firmware on the RAID  
Controller as well as the BIOS of the server, but please check for  
more specifics in the archives.
