Uwe,
Failing sometimes may mean that there is a hardware problem but here are 
some things you can check.

What is the port80 code when it fails?

Can you narrow down the line that fails, northbridge\amd\lx\pll_reset.c?

If it fails in the reset you can try making the pll lock time longer but 
I doubt that it will help.
msrGlcpSysRstpll.lo |= (0xFF << RSTPPL_LOWER_HOLD_COUNT_SHIFT);

You can check the GLCP_SYS_RSTPLL value that is being set.
