[asterisk-users] Sangoma U100 failing every Monday - USB port problem or Wanrouter issue?

Thanks for the input. The errors I pointed out should be available in the
/var/log/messages or messages.1 .2 .3 etc...or in dmesg each time you reboot
the machine. At least that is the case with mine. If you don't have it then
it's I guess very specific to this atom board.  I know someone else added
something along the lines "irq=fixconflict" to get rid of the issue with a
wireless USB mouse showing same symptoms and CentOS. IRQ conflicts is also
one of my thoughts as well but I can't play at BIOS level at this time as
the server is thousands miles away from me.

Regards,
