Yes. It was a hard lockup, no life left.

Thanks for explaining this! Funny thing is that I just got a lockup
on another machine running 2.0.0 with SMC Ultra. So it might lock
up somewhere else, sorry for the NE2000 false alarm.

No SLIP/PPP, no sound, no CD-ROM, no SCSI, both machines with IDE
drives, no kerneld, compiled as ELF with gcc-2.7.2, mostly default
config except:

IP firewalling, accounting, multicasting enabled
IP path mtu discovery disabled
IPX and full internal network enabled
ncpfs enabled (and used)
softdog enabled (didn't help this time)
RTC enabled

Feel free to ask if you need more information.
