Dear All
 
I am working on PowerPC 8266 ADS-PCI board
 
with Montavista Linux with 2.4.20 Kernel to make SCC1, SMC 1& 2
 
in UART mode, SCC2, 3 & 4 in Ethernet mode, and FCC 2 in Fast
 
Ethernet Mode; all in NMSI and not TDM. The drivers provided with
 
2.4.20 Linux on Power PC were refered and reused.
 
http://lxr.linux.no/source/arch/ppc/8260_io/?v=2.4.20;a=ppc 
 
When there are only 3 SCCs used in Ethernet mode and the last
 
SCC in UART mode then the system works well.
 
But when 2 more SMC are added to the UART serial driver, the SCC
 
Ethernet network driver is not working after all ports working for a while.
 
I will be appreciate to hear any pointers and hints.
 
Thanks in advance.
 
Sincerley
