2.1.86 won't get passed init

Hi there, I just found a bug that didn't exist in 2.1.85, but now exists
in 2.1.86 (with the same config options). I am using pgcc 1.01 with
compiler options -O9 and -mpentium. This has worked flawlessly with all
kernels, except the noted gcc 2.8 bug with 2.0.xx kernels. I will
describe what happens.

Init executes, then the system stops after executing the first few lines
of rc.sysinit. When I boot with init=/bin/bash, it loads the command
prompt fine. When I type ls, it locks up after finishing the ls command
(it doesn't return to the bash prompt). The interesting thing is, I can
press ALT-SysRq-K (SAK whatever that means), and it will return me to the
bash prompt. It doesn't seem to matter what command I execute, it won't
return to the command it was executed from. (If you get what I mean). This
would explain why it locks up early in the init sequence (rc.sysinit calls
the first program which never returns).

Does anyone else see these symptoms? I will recompile with gcc 2.7.2.3
later on, and test whether it is in fact the compiler which is the
problem. Meanwhile any pointers would be useful.

Cheers,

Dave.
