You should actually use the 'reportbug' program. That will end
up sending the bug report to this list, but it will also be
recorded in the bug tracking system (BTS) with its own number.

There is really very little difference between architectures above
low-level virtual memory management and some basic device drivers,
and even those are very similar between 32-bit and 64-bit x86.
But you are seeing a BUG message reported from a completely
different place in the kernel:

Please use reportbug to submit a report to the BTS. Don't include
with hwinfo, fstab or mtab. Do include the kernel log from boot time,
the BUG messages (from 'cut here' down to 'end trace') and any
messages logged shortly before.
Ben.
