Solution - AMI megaraid driver doesn't work with Linux 2.4.x kernels

Solution - AMI megaraid driver doesn't work with Linux 2.4.x kernels

[Rafael Martinez]

Hei

The Ami megatrends driver (at least for 471, 475, and 493) does not work 
with 2.4.x kernels.

The solution we got from Ami is to update the firmware of these cards to
version FW G158. This update will fix all the problems with ami
raid-devices in 2.4.x kernel without changing the driver.

We don't know when AMI will release a fixed firmware (hope soon) but we got it by
e-mail. If there is anybody with the same problem I can sent the
firmware-update by mail.

Sincerely
Rafael Martinez

Can you provide the dmesg output of your system after loading the driver
either successfully or unsucessfully.

When it was unsucessfully, it stoppet in the last line with:
sdb: unknown partition table 
(With kernel 2.4.2-2smp from redhat (RH7.1) and "official" 2.4.2, 2.4.3)

The only different between the to instalations is the firmware version
C158 --> G158 of the ami card.

The kernel is a 2.4.2-2smp from redhat (RH7.1). I will test the system with an
"official" ;-) kernel today.
