What's New
==========
ver 2.5.2001.0818 - August 18, 2001
Raid10 data corruption issue is still happening (but very rarely). This driver has more fixes on it.
ver 2.5.2001.0817 - August 17, 2001
Raid10 data corruption issue and power pulling issues are handled.
Ver 2.5.2001.0810 - August 10, 2001
Power Pulling issues are completely fixed. This fix includes the method to avoid the Freezing because of the problem in 649 Chip. Heavy IO and Rebuilding under NT is crashing and is fixed. The problem of not updating the logical drive status to offline when we pull the off the drive from degraded array. Hibernation issue fixed.
Ver 2.5.2001.0802 - August 2, 2001
Now we are checking for more parameters before we decide on the time at which we should break the 31 seconds wait loop. This solved almost all the crashing problems. Now the driver will avoid all most all the cases of freezing (due to the limitation in the CMD chip that the whole PCI Bus will freeze when we read base status register before we issue bus master stop transfer when we pull the power off the drive.
Ver 2.5.2001.0728 - July 28, 2001
We shifted back to issuing the Soft Reset to the drives. But followed the specifications strictly. The possibility of freezing the whole system when we take the power off is avoided completely.
Ver 2.5.2001.0710 - July 10, 2001
Instead of issuing hard reset to the drives we are now issuing the reset through the controller and is looking like working for power failure cases properly.
Ver 2.5.2001.0627 - June 27, 2001
Test release with 40 seconds delay introduced for hard reset.
This was done for the slave disk removal issue you are working on now.
