Subject: Another SATA device with spurious NCQ completions
Date: Mon, 25 Jun 2007 14:34:59 -0400 [thread overview]
Message-ID: <46800AD3.7050803@redhat.com> (raw)

The following error consistently appears at apparently random intervals in syslog:
kernel: ata1.00: exception Emask 0x2 SAct 0x1001 SErr 0x0 action 0x2 frozen
kernel: ata1.00: (spurious completions during NCQ issue=0x0 SAct=0x1001
FIS=004040a1:00000800)
kernel: ata1.00: cmd 61/08:00:39:2b:cc/00:00:08:00:00/40 tag 0 cdb 0x0 data 4096 out
kernel: res 40/00:00:39:2b:cc/00:00:08:00:00/40 Emask 0x2 (HSM violation)
kernel: ata1.00: cmd 61/08:60:e1:2b:cc/00:00:08:00:00/40 tag 12 cdb 0x0 data
4096 out
kernel: res 40/00:00:39:2b:cc/00:00:08:00:00/40 Emask 0x2 (HSM violation)
Controller is ATI SB600 using the AHCI driver.
64-bit DMA is disabled.
Disk is:
ata1.00: ATA-7: ST3160812AS, 3.ADJ, max UDMA/133
Can't we just turn off NCQ automatically when this happens?
