Has anyone else noticed this regression?

Hello,

I just attempted to upgrade a system from 2.6.17 (gentoo revision 8) w/
1.20.0X.13 to 2.6.20 (gentoo revision 4) with the in tree arcmsr driver.
On the 2.6.17 kernel there are 2 ~4TB partitions that are visible on
the system as /dev/sdb1 & /dev/sdc1.  When the system is booted with the
2.6.20 kernel /dev/sdc1 is gone and /dev/sdb1 is properly reported as a
4TB EFI partition but fsck rejects the the filesystem as corrupt.  Is
this a regression or has there been a fundamental change in the way
arcmsr represents the array to the block layer?

Here is the info on the RAID card:

    Controller Name     ARC-1170
    Firmware Version    V1.39 2005-12-13
    BOOT ROM Version    V1.39 2005-12-13
    Serial Number   Y605CAAVAR700117
    Unit Serial #    
    Main Processor  500MHz IOP331
    CPU ICache Size     32KBytes
    CPU DCache Size     32KBytes / Write Back
    System Memory   256MB / 333MHz

Any idea as to what's going on?

Thanks,

-J
