Hi,

What could that be?
VIA VT6421A mini-PCI card and SATA SSD from Transcend. IXP425 (ARM)
little-endian CPU. 128 MB RAM - VT6421A can access only the first 64 MB
of system RAM, but there is bounce buffering (a la swiotlb) for the
rest.

Sometimes it produces:

ata1.00: exception Emask 0x12 SAct 0x0 SErr 0x1000500 action 0x6
ata1.00: BMDMA stat 0x5
ata1: SError: { UnrecovData Proto TrStaTrns }
ata1.00: cmd c8/00:20:b7:18:38/00:00:00:00:00/e0 tag 0 dma 16384 in
         res 51/40:20:b7:18:38/00:00:00:00:00/e0 Emask 0x12 (ATA bus error)
ata1.00: status: { DRDY ERR }
ata1.00: error: { UNC }
ata1: hard resetting link
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata1.00: configured for UDMA/100
ata1: EH complete

Any ideas?
