megaraid problem

Hi to everyone.

I have a megaraid raid card :

Vendor: MegaRAID Model: LD0 RAID5 52095R Rev: E
Type: Direct-Access ANSI SCSI revision: 02

We used to run 2.4.23 very well for a long time, but we need to upgrade because of all the security problems (never too late :) to 2.4.25. I've tried for days with no luck; booting gives us :

megarid: Waiting for 3 commands to flush: iter:1000
megarid: Waiting for 3 commands to flush: iter:2000

and so on. I tried to copy the megaraid2.c/megaraid2.h from 2.4.23 (who knows...) but it doesn't work better.

I am out of ideas here, so I just wonder if someone has a solution.

Thanks.
