RaspberryPi pukes on software RAID1 over USB

[PROBLEM]
I have 2 USB drives attached to a Raspberry Pi, mirroring one 500 GiB partition using Linux software RAID1.
In general, the RAID1 is up and running, but:
  • Synchronizing the RAID can't be done on the Raspberry Pi, because it causes the OS to freeze.
  • When the RAID is properly in-sync, copying larger amount of data onto the RAID1 partition causes the same freeze/lockup.
It comes without a warning, but I've found this in /var/log/messages:
ERROR::dwc_otg_hcd_urb_enqueue:515: Not connected
Haven't figured it out yet completely if this is related, but there are others having problem with USB, seeing the same error message:
[SOLUTION]
Thanks to the posts mentioned above, I was hinted into questioning the power supply. The power supply used was an "Emporia" with 1A and doing a good job for around 2 years already, but still.
I've replaced the Emporia power supply with a "Navilock" (also 1A) and now it seems to work!
  • Old power supply: Emporia travel charger "MSH-TR-018"
  • New power supply: Navilock ultra flat "61863"
Details about the kernel messages are in the post below.

Here are the interesting bits of the kernel logfile (/var/log/messages) before the crash:
NOTE: "..." means that the message was repeated several times.

Code: Select all
