A BUG() is something like an assertion. Basically this means that a developer
thought that a certain situation should never be happen and if it does,
execution should stop. It is possible to ignore this and continue executing:
config BUG
bool "BUG() support" if EXPERT
default y
help
Disabling this option eliminates support for BUG and WARN, reducing
the size of your kernel image and potentially quietly ignoring
numerous fatal conditions. You should only consider disabling this
option for embedded systems with no facilities for reporting errors.
Just say Y.
A kernel oops is basically a crash. This can be caused by bad memory accesses
and things like that.
