I have a similar issue running 5.3 STABLE on a machine which runs fine with 5.3 BETA7.
Booting into safe mode works fine. Any other way, and it gets ATAPI errors or SCSI errors (if I take all ATAPI stuff out of the kernel).
Still trying to find the real source of the problem...
Good luck,
Lapo

I am unable to install FreeBSD 5.3-RELEASE on my Soekris net4801, which has a SanDisk Ultra II 512MB Compact Flash card as a hard drive. The kernel probes the drive just fine but when it comes time to write or read from the drive, specifically in sysinstall, I get;
ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=0 ad0: FAILURE - READ_DMA timed out ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=0 ad0: FAILURE - READ_DMA timed out ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=0 ad0: FAILURE - READ_DMA timed out ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=1 ad0: FAILURE - READ_DMA timed out
Then sysinstall says;
"ERROR: Unable to write data to disk ad0!"
To do this manually, with fdisk, disklabel and newfs works up until the computer has rebooted and tries to load the root filesystem. It hangs for a little while then starts spitting out those READ_DMA errors and finally refuses to mount ad0s1a as root.
Disabling DMA in loader.conf doesn't seem to have any effect.
Any ideas here would be much appreciated.
