It appears your USB disk hits read errors:
KERN: usb_disk: receiving the command status wrapper failed: Operation timed out
KERN: usb error control pipe 85: timeout waiting for queued request to complete
KERN: usb error ehci 2: qtd (0x789f00) error: 0x80008148
KERN: usb_disk: write failed: Operation timed out
KERN: usb_disk: command status wrapper is not valid: 0x0
KERN: usb_disk: write failed: General system error
KERN: PageWriteWrapper: Failed to write page 0xffffffff8b818b20: General system error
Then later on, we get segmentation faults in runtime_loader and elsewhere when trying to start programs, which is expected after that.
