Hallo Everyone...
Some bad news after godd news...
i'm finally sure that on p133 everything works right...
Now i'm testing scc on 486dx2 (real destination of scc..)...
Please refer to my last msg for the initialization proble....
After the card is running i can see the pkts in rx... and everything seem
to be right...
When i try to connect another station, usually linux crashes....
After millions of test i've noted this:
Linux crashes when there are both rx interrupts and tx interrupts...
If i noly receive on transmit no problem.. When i try to connect another
station while scc is receiving, the computer reboots...
This does not happen on p133....

It's now an irq problem surely!! But i don't know if the first cause is
the pc or the groups Linux-PC-sccinit...

Where may i found some debug infos on this crashes?? Please note that i've
no oops on Linux...
I tried to define SCC_DEBUG... But i've not found anything in log's
files....

Some idea??
Thanks
Good holidays...
Luca
