That means we need find out another way to detect there have 3G modem or not, unfortunately I only know one way is check "type aa in dmi" and I already implemented in acer-wmi, looks like Acer 8930G have no "type aa" in dmi. I thought your machine have wifi and bluetooth, but doesn't have internal 3G module. Could you please help attach dmi_decode on this bug? - dmidecode > dmidecode.log If you have time, I appreciate you can help: - Remove wifi module then dump "dmidecode > dmidecode_without_wifi.log" - Remove bluetooth module then dump "dmidecode > dmidecode_without_bt.log" Then we can compare the above dmidecode log, if we are LUCKY then we can find out another "OEM-specific Type" like "type aa" that is mapping to devices exist state. Of course we still don't know which bit represent 3G modem, the original acer-wmi design is enable 3G capability by default, I thought we need disable it until we find out a way to detect internal 3G device exist or not. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
