Are you experiencing network hangs and/or "timeout" messages on the=20 > console? If yes, please provide a _brief_ description of the problem. After Bill Moran set me up with access to his machine that is experiencing bce timeouts, I determined that his instance of the problem is due to a bce driver bug (which triggered an INVARIANTS sanity check when configured, and panicked). I suspect there are several seperate problem here though (this one did not involve em at all). Nevertheless, a similar driver bug may be to blame in other cases too. So, can everyone who is seeing some kind of driver watchdog timeout problem please recompile their kernels with the following options: option INVARIANTS=20 option INVARIANT_SUPPORT and confirm (in addition to the information previously requested) whether or not their kernel panics in conjunction with the timeout. If yes, then you can follow the information in the developers' handbook chapter on kernel debugging to proceed with gathering the information we'll need to proceed.
