SubjectPPP panic with 2.0.20
Pentium 90, 64m ram, PCI
Kernel 2.0.20 compiled as ELF
GCC 2.7.2, libc 5.3.12
PPP 2.2.0f
No modules

At the time of the panic, there were 25 ppp channels open.
I don't think it's flakey hardware. This machine runs for 15+ days on
1.2.13 and ppp 2.1.2 without panics, yet on 2.0.20 this panic came up
within the first 4 hours uptime.
