Subject: [PATCH v2 1/1] x86/kernel: Update bug_at() head message

First of all, %*ph specifier allows to dump data in hex format using the
pointer to a buffer. This is suitable to use here.

Besides that Thomas suggested to move it to critical level and replace __FILE__
by explicit mention of "jumplabel".
