1 Release Date : Mon. March 10 11:02:31 PDT 2008 -
(emaild-id:megaraidlinux@lsi.com)
Sumant Patro
Bo Yang
2 Current Version : 00.00.03.20-RC1
3 Older Version : 00.00.03.16
1. Rollback the sense info implementation
Sense buffer ptr data type in the ioctl path is reverted back
to u32 * as in previous versions of driver.
2. Fixed the driver frame count.
When Driver sent wrong frame count to firmware. As this
particular command is sent to drive, FW is seeing continuous
chip resets and so the command will timeout.
3. Add the new controller(1078DE) support to the driver
and Increase the max_wait to 60 from 10 in the controller
operational status. With this max_wait increase, driver will
make sure the FW will finish the pending cmd for KDUMP case.
