I have a Powerboot 1999 and I'm having a few annoyances with it. I'm
currently using the stable rsync kernel from linuxcare. The following is
happening:
* Serial drivers - At least when talking to the modem, it will occasionally
cease to work. I use pppd to connect, and when it disconnects I cannot
reconnect. Once this happens, anything that tries to open the port get
an I/O error. If I unload the serial module and then reload it, the
problem goes away for a while. This started happening around 2.2.15.
* MESH Driver - It won't work with my scanner. The scanner works fine
under MacOS and used to work under Linux x86. It has problems with
disconnects. Also, once I use it then sleeping and awaking will locks up
the machine. Also, unloading the MESH module and reloading it locks up
the machine.
* Ethernet driver (BMAC) - The driver will occasionally lock up under heavy
load (I haven't seen this yet with 2.2.17, though). If I define an alias
address, bringing down the alias address will also bring down the main
address (this is still happening under 2.2.17). Unloading the ethernet
driver and loading it again causes a lockup.
I'm also seeing random lockups after long periods of running under
heavy load, but this is new and I'm thinking it may be a heat problem.
But just in case, I'll say it.
I'm posting this to see if anyone is aware of these problems. I'm
willing to work on them, but I don't want to duplicate work. But I
would like to hear from the responsible parties for each driver to
know what to do.
Thanks,
Corey

Dan Malek recently "ported" a workaround for a HW SCC bug which seem to
fix such problems. (The SCC get stuck sometimes when receiving certain
kinds of bad characters). I'll try to get that merged ASAP.

Paul ? Any clue ? MESH is still a weird beast to me ;)

I've not experieced that before, there are some known issues with bmac
(HW bugs uncovered by comments in Apple's Darwin source code) but AFAIK,
nothing that cause a kernel lockup.

heavy load, but this is new and I'm thinking it may be a heat problem.

It may also be a RAM problem. Some Lombards are known to have memory
controller (or RAM, we don't know for sure) problems.
Also, which boot method are you using ?
