>Description:
Using the puc driver in an SMP machine causes a kernel panic. This is repeatable in at least two differnt machines. The same puc card works 100% if the same machine is using a non-smp kernel.
>How-To-Repeat:
Use a puc serial device for ppp in an smp machine. shortly after you start passing traffic it is likely to panic. From the backtrace the panic always occurs in the serial interrupt routine.
>Fix:
Current workaround is to run a non-smp kernel.
