I got a similar problem when I connect my HDD with a DMA33 cable last
time when I was trying to install 6.0-PRERELEASE:
ad0: 190782MB <Seagate ST3200826A 3.03> at ata0-master UDMA100
Trying to mount root from ufs:/dev/ad0s1a
ad0: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA = 12623
ad0: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA = 12623
ad0: FAILURE - READ_DMA status = 51 < READ, DSC, ERROR> error = 84<ICRC,
ABORTED> LBA = 12623
g_vfs_done():ad0s1a[READ(offset = 6430720, length = 4096)] error = 5
vnode_pager_getpages: I/O read error
vm_fault: pager read_error, pid 1 (swapper)
init died (signal 6, exit 0)
panic: Going nowhere without my init !
Uptime: 2s
Cannot dump, No dump device defined
I also tried to disable DMA to make that disk work, but later
I found it was caused by a DMA33 cable. That disk worked fined
after I replaced that cable.
