>Description:
The latest sparc64 CD install image fails to start due to the transfer mode for aceride not downgrading to PIO4. This is a known issue with DMA transfers and ATAPI devices on this particular chip. The NetBSD 9 installer handles this situation and starts as expected.

This issue probably isn't specific to sparc64, but this chip is very common in later non-SCSI Sun machines (like this one).
