Subject: Other Problems with Marvell Driver - 7042 (2.6.23)...

I am running the 'latest' kernel retrieved from Kumar Gala's
Powerpc git tree (mainly because I am running on a MPC8548 board) 
and it appears to be in the full 2.6.23 version while the sata_mv 
driver version seems to be 1.01. 

I have searched the archives, and there has been some discussion
of a regression in the Marvell driver, but I seem to have a 
different symptom from Olaf's (I am not running a 64bit kernel - 
and I am *not* running with large (36bit) physical and resources - 
so I wouldn't have the same type of IOMMU issues)

Below in the error output (using ATA_DEBUG) the driver sees the 
two drives (3 partitions on /dev/sda & 2 partitions on /dev/sdb)
and apparently sets up everything correctly for standard access...

But, when I try to mount a partition - it freezes up and gets I/O
errors?
Can someone give me any hints of things to try?

Thanks in advance...
