[Sergio Callegari <sergio.callegari@xxxxxxxxx>]

Tried 3.10.5 from the mainline ppa.

The situation if possible is even worse.

At boot I get tons of I/O errors on the usb3 disks that make up the raid
components.

In dmesg I find

... and only from this point on the system seems to be able to mount the
raid.

It is totally unclear to me at this point if latest kernels have the
same problem as 3.8, a completely different problem or both.

Title:
  Linux software raid + usb3 storage + heavy disk activity = recipe for
  disaster in raring?

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I have a system with a Nec PCI USB 3 adapter (Renesas Technology Corp.
  uPD720201 USB 3.0 Host Controller) with a Lindy USB3 disk case for 2
  disks attached to it (JMicron Technology Corp. chipset) and two 1TB
  disks inside.  The Lindy disk case is configured to show the 2 disk
  units (in windows it supports fake raid to with proper dip-switch
  configuration).

  Linux is configured to see the two disks as a software raid 1 unit.
  LVM is set up on top of the raid.  Ext4 partitions are created in LVM.

  Apparently things work just fine.  However, if I have heavy disk
  activity (e.g. copy a large iso file to the raid storage), there are
  very frequent issues. In the worst case the machine freezes (flashing
  leds) trashing all the last data written on the raid storage. When the
  machine comes up the raid starts resync which is a painful activity.
  No visible oops, nothing in syslog. In the best case, the array simply
  looses sync.

  Even when things work fine, the disks in the array make clunky noise
  that does not seem proper.

  Also tried with a VIA USB3 controller and with the motherboard
  integrated USB2 controllers. With USB2 things are much slowlier, but
  the result is invariably the same.
