Re: dl2k: PCI parity error

Hello list,

Not sure if this is the best place to report this.  I seem
to be having a conflict of sorts and believe it may be a
dl2k issue.  The card is a Dlink 550t gigabit pci-64 card. 
When connected to the pci-64 slot on the mb which shares an
IRQ with the onboard SCSI controller, the SCSI subsystem
starts reporting PCI parity errors.  If I move the NIC to a
pci-32 slot, the errors go away.

Do you have any other 64bit slots?

scsi0: PCI error Interrupt at seqaddr = 0x9
scsi0: Data Parity Error Detected during address or write data phase
scsi1: PCI error Interrupt at seqaddr = 0x9
scsi1: Data Parity Error Detected during address or write data phase
scsi1: PCI error Interrupt at seqaddr = 0x9
scsi1: Data Parity Error Detected during address or write data phase
scsi0: PCI error Interrupt at seqaddr = 0x8
scsi0: Data Parity Error Detected during address or write data phase
scsi0: WARNING WARNING WARNING WARNING
scsi0: Too many PCI parity errors observed as a target.
scsi0: Some device on this bus is generating b ad parity.
scsi0: This is an error *observed by*, not *generated by*, this controller.
scsi0: PCI parity error checking has been disabled.

This is using a 2.6.15.4 kernel but I can certainly update
if that will help.  Is this likely a dl2k issue?  The
driver does seem a bit dated.

The driver is mostly unmaintained.  I did a fix a month or so ago which
fixed a DMA free issue, but that doesn't sound like the problem you have
here.

There is another error I am seeing that I haven't had time to track
down, where the adapter appears to be DMA'ing somewhere its not supposed
to.

I would be suprised if either of these caused a SCSI data parity error.

Thanks,
Jon
