[Kernel-packages] [Bug 1881134] Re: amdgpu crashes in mode_support_and_system_configuration
This is now fixed upstream in this commit: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=7ad816762f9bf89e940e618ea40c43138b479e10 This might be important enough to patch in Ubuntu eventually. Currently virtualized 32-bit guest operating systems combined with amdgpu driver on the host cause random crashes. -- 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/1881134 Title: amdgpu crashes in mode_support_and_system_configuration Status in linux package in Ubuntu: Confirmed Bug description: When switching window from gnome-terminal to firefox, the amdgpu kernel driver suddenly crashed.
