And I have similar problems with CURRENT of a few days ago. When I configure my kernel to use the new ata driver, it hangs when booting. I plan to reproduce this problem this weekend, with a more recent CURRENT. I think the problem is caused by the RZ1000 EIDE controller on this type of motherboard. I suspect that the new ata driver deals with interrupts in ways somewhat different from the old wd driver. According to the Intel documentation, interrupts during data transfers may cause data corruption. This RZ1000 issue has been discussed on this list a few weeks ago, without a real solution.
