Replying to [comment:4 waddlesplash]:
> @anevilyak: I was pretty sure, from talking to cdesai on IRC, and from
looking at the stacktrace, that this is the kernel's fault. After all,
it's just after the entry point (_start) no? (And there were some very
similar bugs surrounding acquire_spinlock before, but they occurred after
boot had finished).
Except those are also frequently provoked by using the on-screen debug
output option, that one can mess with timing in a number of ways and
really shouldn't generally be used. It's really only meant for debugging
very early boot issues. More useful would be the syslog output from a
perfectly normal boot attempt, i.e. by attempting to boot normally, then a
soft reset, then accessing the previous boot's in-memory syslog via the
boot loader. Most likely this one's a device driver issue.
