[Kernel-packages] [Bug 1667160] Re: Kernel panic when using rtlwifi since 4.8.0-1025 on RasPi 2
I'm unable to reproduce this bug: $ lsusb Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp.

[Kernel-packages] [Bug 1667160] Re: Kernel panic when using rtlwifi since 4.8.0-1025 on RasPi 2
Did anybody check the current kernel from zesty? I'm thinking about upgrading, but don't want to render the thing unbootable because there's no working kernel left. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1667160 Title: Kernel panic when using rtlwifi since 4.8.0-1025 on RasPi 2 Status in linux package in Ubuntu: Confirmed Status in linux-meta-raspi2 package in Ubuntu: Confirmed Bug description: I have a Raspberry Pi 2 running Ubuntu 16.10 without problems.
