When I remove the interrupt definition from the DTS (to cause
irqpolling), the ata driver gets stuck in a loop displaying the
following. Does anyone have any insight?
ata1.00: status: { DRDY }
ata1.00: qc timeout (cmd 0xec)
ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4)
ata1.00: revalidation failed (errno=-5)
ata1: hard resetting link
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata1.00: configured for UDMA/100
ata1: EH complete
ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 dma 4096 in
res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x20 (host bus
error)
