Two users of Debian on the QNAP TS-419P have seen the following
"Unable to stop eDMA" error in dmesg. Rebooting makes the problem go
away. Can someone explain what this problem is about and whether this
might be a bug in the kernel?
The QNAP TS-419P uses the Marvell Kirkwood SoC and offers 4 SATA ports
via an 88SX7042 chip connected via PCIE (the SATA on the SoC is used
for 2 eSATA ports).

The SError being set to all 1s suggests something strange has happened,
like the hardware going cuckoo and returning PCI master aborts..
