Hi all, I am getting kernel panics related to the rtl8180 driver. I have a RTL8185 card in my desktop and am using debian testing with kernel version 3.10.5.

I've got kernel panics about 20 times in the last month but had not been able to find the first oops message until now. Most of the time the panic happened when the monitor was in sleep mode so I wasn't able to see the oops. Other times, a useless drm_fb_helper_restore_fbdev_mode oops hid the first oops. I then set up kdump to get the oops. I suspect the rest of the panics have also been due to this. I don't have any steps to reproduce; it seems entirely random. Sometimes it happens after weeks, sometimes within 10 minutes. There's also zero traffic on the wlan0 interface as it is in managed mode and not associated to any access point. I have the full memory dump taken after the crash and an associated vmlinux file in case we need it to troubleshoot this further.
