USB: Buffer I/O error on device dm-0, logical block XYZ
Andreas
on heavy disk I/O my external USB device gets re-mounted read-only.
(Ok - scp with 2,5MB/s over WLAN)
After this i get EXT3-Errors.
I've already:
- tweaked kernel parameters (see below)
- changed entries in sys-fs
The only thing that works is if i remove the ehci module for USB2.0.
SysLog-Errors:

This is the real killer here, everything else is just collateral damage.
Looks like your USB host controller indicated a fatal host system
error, apparently because of an error on the PCI bus, which seems rather
bizarre. Some kind of hardware problem?
