https://bugzilla.kernel.org/show_bug.cgi?id=204227 --- Comment #13 from Mirek Kratochvil (exa.exa@xxxxxxxxx) --- After the BIOS upgrade the kernel parameters can be removed, but the kernel (5.2.16) now locks up when entering XFCE (it survives lightdm though). The error is almost same as as in the posted dmesg; I'll attach mine with backtraces in a few seconds. Highlights: This gets printed out before each warning: [ 66.159175] [drm] pstate TEST_DEBUG_DATA: 0x36F60000 R08 gets increased by some value between 49 and 56 after each next warning (the value is sometimes in R10) Userspace seems working otherwise (the logs are from syslog), just the display won't show anything. I will try a few other kernels available for debian and eventually bisect. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
