Source: linux Followup-For: Bug #949369 Dear Maintainer,
I experienced the same crash after upgrading to kernel series 5.4.x (namely to 5.4.8) in mid of January. The crashes of the system were quite frequent (every few hours, making the system unusable). After few experiments I ended up with the linux kernel 5.5.0-rc5 from unstable, which seems to work relativelly well. However, today I got the same crash already twice, despite more than month of using it. There are numer of reports about the problems related to the i915 driver in the 5.3.x-5.5.x kernel series: https://bbs.archlinux.org/viewtopic.php?id=250765&p=7 https://linuxreviews.org/Linux_Kernel_5.5_Will_Not_Fix_The_Frequent_Intel_GPU_Hangs_In_Recent_Kernels https://forum.manjaro.org/t/random-freezing-with-resetting-rcs0-for-hang-on-rcs0/119313/29 https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.5-Intel-Missed-Graphics Kernels 4.19.x in buster seems to be fine.
