[Galaxy Note GT-N7000 Android Development] samarium:
I've been looking at TWRP compressed backup in recovery, to save a bit of space, and make it quicker to rsync the backup off the phone. It causes recovery crash, looks like kernel crash, as phone reboots.

I noticed it on 1218 ROM, when I tried to backup before installing 1219. Crashed twice, so saved last_kmsg and did Ti backup, then flashed 1219.

Tried TWRP compressed backup with 1219. Crashed again. Tried TWRP uncompressed backup. Didn't crash.

Below is what I think is the relevant part of the last_kmsg. Full here http://paste.ubuntu.com/6600026/

Any ideas?
