>Description:
I use this machine as a non-X geek station. I set up wsvt25 as the console 
settings and use tmux, along with mc, irssi, vim, the works. I noticed before 
that the display is sometimes quirky unless I revert to vt220, but nothing too 
important. Today, after installing finch, the system panicked twice in a row 
when I tried to used finch's alt+n (next window) shortcut - first time - and 
second, right after starting tmux. Here are the crashes and my dmesg (I used 
crash -M corefile -N kernelfile) :
