https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228628 Bug ID: 228628 Summary: Kernel panic after resume Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: freebsd@justmail.de Since upgrading CURRENT from r333740 to r334167 I'm experiencing reproducibly Kernel panics. Before the update i did not have any of those. Steps to reproduce: In my case i have to repeat these steps several times (2-7x), then the panic (backtrace below) occurs. 1. suspend 2. resume 3. start firefox Hardware: Lenovo Thinkpad T450 Laptop Software: FreeBSD CURRENT with Kernel-Config GENERIC-NODEBUG, drm-stable-kmod from ports Additional: I've built and installed kernels until the error appears: The last working revision is r334117, the first not working is r334123. Revisions 334118-334122 of the kernel did not build, so i cannot try these. Backtrace: __curthread () at ./machine/pcpu.h:231 231 ./machine/pcpu.h: No such file or directory.
