Hello,

I've recently made a few changes to my machine, and one of the unfortunate
side effects is
the following error.

Mar  5 17:15:32 localhost kernel: [    7.396912] ata14.00: qc timeout (cmd
0xa1)
Mar  5 17:15:32 localhost kernel: [    7.398906] ata14.00: failed to

This causes my boot to pause while the kernel probes ports, which I'm fairly
confident do not exist. I have x5
sata devices attached to my computer. They are all reported, and work
great.  I'm not sure where it's getting
"ata14 from".

I recently RMA'd my motherboard, and one of the first side effects I noticed
was my ethernet (eth0) was
completely missing. Through google, I found out udev had written the old
device info from my previous motherboard
in /etc/udev/rules.d/70-persistent-net.rules.  Simply deleting this file and
rebooting fixed that.

Is it possible something very similar is going on here, but with my  ata
devices?

I also swapped out a few disks today. I dropped an old raid0 in favor of an
ssd, but everything went fine
as far as I can tell.  I'm not positive, but I think this error existed
before I did this.

Thanks for your time,
Alan
