Please consider this for 5.3. --- Additional comment from mike.miller on 2008-07-16 16:54:18 EDT --- Created an attachment (id=312000) Patch to dynamically set queue depth This patch changes the way we set queue depth for each controller. Instead of arbitrarily assigning some value we now read the controller config table to determine how many commands are supported by the controller. We then subtract 4 to leave room for ioctls. The latest controllers added support a mode of operation called Zero Memory Raid (ZMR). In this mode they only support 64 commands. So under load the user is bombarded with annoying "fifo full" messages. We also spin until something completes so IO becomes backed up and system performance is very poor. This is a bug fix. Please consider this for inclusion in 5.3.
Created attachment 313396 [details] Change the names of latest generation controllers. This patch removes 5 proposed new controllers and changes the marketing name of the remainig 5.

Created attachment 326168 [details] Patch to update controller names, fix bug, add 2 new controllers This patch updates controller names and adds 2 new controllers. Those names/IDs are already upstream. It also addresses a bug for the P700m controller and all later controllers. The entry for the P700m was missing in the product table. The previous patch also addressed this bug but was not documented as such. Please use this patch for Update 8.
Since RHEL 4.8 External Beta has begun, and this bugzilla remains unresolved, it has been rejected as it is not proposed as exception or blocker.
This patch was rolled into the main cciss BZ for 4.8, 454643. Closing as duplicate. *** This bug has been marked as a duplicate of bug 454643 ***
