Comment 1 SpanKY gentoo-dev 2014-11-05 16:28:36 UTC
save the current buffer:
 dmesg --color=never -r > log

then see if it still crashes:
 dmesg --color=always -F log

if so, attach that log file here
Comment 2 BRULE Herman 2014-11-05 16:36:42 UTC
dmesg: these options aremutually exclusive: --color --raw
dmesg --color=never -> crash
dmesg -r > log work, see the attached file
dmesg --color=always -F log -> crash

Comment 4 BRULE Herman 2014-11-05 16:38:32 UTC
dmesg --color=always -F log -> don't crash on my x86, only on my odroid-u3-1
If needed I can open you a private access.

I cannot reproduce this :/
Comment 8 Alexander Tsoy 2015-01-18 15:17:59 UTC
Looks like this bug is only reproducible on ARM. Confirming it on Raspberry Pi too.
