Has anyone else noticed this regression?

Subject: difference between 1.20.0X.13 & 2.6.20 in tree driver?

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
