Do you build your own kernel, or are you using openSUSE's supplied version? If

Lost network this morning, but no error message. We restarted the
network service, things were back up and the error message was logged
then:
rtl8192ce:rtl92ce_get_hw_reg():<0-0> switch case 92 not processed
So I think this is happening when the interface is put down, and is
probably not related with the loss of connectivity. But it would be
good to understand and fix it nevertheless.
92 is HAL_DEF_WOWLAN. I see it is handled differently in 2 other
rtlwifi drivers: rtl8192cu ignores it, while rtl8821ae processes it:
case HAL_DEF_WOWLAN:
if (ppsc->wo_wlan_mode)
*((bool *)(val)) = true;
else
*((bool *)(val)) = false;
break;
I don't know what is the appropriate course of action in the case of
the rtl8192ce. Let me know if you need anything else from me.
As the RTL8192CE does not support WOWLAN, the correct response is to ignore that
call. Clearly, it has nothing to do with your network drops. One thing you might
do is add the appropriate file in /etc/modprobe.d/ so that the module is loaded
with the "ips=0" option to see if power save is messing up.
I am in the process of fixing all the instances where the log entry for the
default case does not output the switch variable. With these patches, I will
also handle the HAL_DEF_WOWLAN case.
I'm sorry about my original comments regarding patching the kernel. I sent that
E-mail before I even read your name and address. As a long-time openSUSE user, I
certainly recognize your name and your abilities.
