Hello,
[...]
I think those are among the first and last dmesg we want, near the time of trouble. Giving us an extra paragraph before and afterwards probably wouldn't hurt either.

Hmmm... These lines look weird:
Oct 26 23:53:09 titanic kernel: usb-storage: Bulk Command S 0x43425355 T 0x4d1a0 L 32768 F 128 Trg 0 LUN 0 CL 10

Oct 26 23:53:10 titanic kernel: usb-storage: Bulk Status S 0x53425355 T 0x8004d1a0 R 0 Stat 0x0
Why suddenly "CL 6" ??? It's around the time of the data phase error...
