I've been doing some testing (and general using) over the past little while 
with MOL versions (0.9.70) rsync'd from around the tenth through Friday 
morning.  Most recently compiled against a fresh custom 2.4.24-ben1 with 
self-compiled alsa 0.9.8 modules built from alsa-source debian package, 
running on an up to date Debian Sid (unstable) system.  Output from 'lspci' 
at the bottom of the message, and my most recent mol.0.log file is attached, 
I'm booting OS 8.6 under MOL from an MOL-only external scsi disk.  Behavior 
has not changed noticeably at all through rsyncs, recompiles, move from 
kernel 2.4.23-ben1 to 2.4.24-ben1, etc.

I'm having a problem; MOL will frequently lock up my whole machine.  Pegs the 
cpu meter, apps don't respond anymore, keyboard is unresponsive (ctl-alt-del 
doesn't reboot) and essentially renders my entire system unusable.  The way 
it crashes seems to be somewhat of a progression - if I'm quick I can maybe 
do an 'ls' on a free xterm or logout but apps and stuff hang pretty quickly 
after that.

I'm often able to switch to another console (vt1 or 2, for instance) but 
sometimes I gets stuck in vt2 or trying to login in vt1 hangs after typing my 
username and hitting return.  If the entire machine hasn't gone down hard I 
can sometimes get in from the network - appletalk will often respond when MOL 
won't, and sometimes I'm able to ssh in from another box and poke around a 
little.  Running 'ps aux' one of the times (didn't think to copy off the 
output, sorry) told me that 'mol' had become a zombie process and the 
'/usr/local/lib/mol/0.9.70/bin/mol' processes were in an uninteruptable 
sleep.  Any shutdown processes that I ran ended up in an uninteruptable sleep 
state as well.  

I'm not entirely sure what type of actions in MOL trigger this behavior - It 
_seems_ to be network access related - it will consistently do funny things 
when trying to open an appletalk volume.  If I mount a disk from the chooser 
and double-click it to open it, Mac OS will hang after displaying the first 
zoom rectangle. If I go to 'Recent Servers' in the Apple menu, it opens fine 
but if I try to open a subdirectory it displays the first zoomrect and sits 
there.  Force Quitting the finder fixes that, though.  Other than that, it 
seems rather random.  I admittedly haven't done anything with TCP/IP 
networking.  

Also, one of the times MOL hung up this afternoon, I went back over to KDE and 
tried to kill it from the shell.  Shell hung after the first ctl-C and 
message, so I quickly hit my logout button (it worked!) and told the machine 
to reboot.  It shut down KDE/X and told me the system was going down NOW, but 
it hung there.  I ssh'd in and it was about the same as the other time I got 
in that way, mol was Zombied, I managed to kill a couple of the sleeping 
'/usr/local/whatever/bin/mol' processes but one was in an uninteruptible 
sleep (along with about five shutdown processes) and one was still using a 
bunch of CPU and also refused to be killed.  I  don't know if it's relevant, 
but I also noticed on my console here I was getting 'IN= OUT=tun0 
SRC=192.168.40.1 DST=192.168.40.255 Len=78 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF 
PROTO=UDP SPT=137 DPT=137 LEN=58' (hand copied) messages every so often and 
checking /var/log/messages from my ssh shell revealed they started after the 
mol kernel modules were insmoded.  I seem to remember something similar to 
that a while ago on the list but I couldn't find it. :^/

Anyway, sorry for the length of this thing.  I'd really like to fix this and 
be able to use MOL for stuff without rebooting my machine a couple times a 
day, but I'm kinda stuck right now.  If I forgot something, whack me and I'll 
do it/find it/whatever. :^)
