Our product have two 8139 netcards, some customers use it as router. After about one hour the product will crash when playing video. There is no output in the serial port. After i turn on the option CONFIG_DEBUG_BFIN_HWTRACE_EXPAND,
the product is very stable, but the performance is very bad. Can you tell me how to trace the crash problem for no output?
The kernel version is:
Linux 188.8.131.52-ADI-2010R1 #18 Fri Aug 5 07:37:12 UTC 2016 blackfin GNU/Linux
