Description

With latest kernel (including commit 6b08c773ea455c6ed5d929050129ad4e9ff5abe0),
I git 2 panics with the same message. The dumps are at
leaf:~rumko/crash/kernel_map/{k,v}*5 and leaf:~rumko/crash/kernel_map/{k,v}*6

The backtraces are different, so posting both:

Unread portion of the kernel message buffer:
