Comment 5 for bug 529363

This might have something to do with the issue. Here is what I find in dmesg while attempting to access a drive connected to the hpt370. I see the same timeout when trying to install grub on the drive. I booted Ubuntu from the 9.10 i386 install CD live session. The driver the live session is using is pata_hpt37x.ko.
