Bugzilla Automation <[email protected]> has asked freebsd-x11 mailing list <[email protected]> for maintainer-feedback: Bug 245923: graphics/drm-fbsd12.0-kmod: 12.1-stable crash on loading i915kms.ko https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245923 --- Description --- After upgrading 12.1-STABLE from r359345 to r360192, with graphics/drm-kmod and graphics/drm-fbsd12.0-kmod rebuilt and reinstalled together with the new kernel, the system crashes when loading i915kms.ko. When loading the module via kld_list in /etc/rc.conf at boot, screen goes blank and system stops responding until a power cycle. If booting without loading the module and loading it with kldload manually, the screen goes blank and reboots after some time. In the latter case a crashdump is found at the next boot. Hardware is an Acer C720 Chromebook, using a Celeron 2955U. The graphics controller shows in pciconf -lv as "Haswell-ULT Integrated Graphics Controller". Kernel config is based on GENERIC, but with options WITNESS and WITNESS_SKIPSPIN added. I don't know much about debugging kernel dumps, but if someone tells me how to do it I'm ready to try getting data out of the existing dump. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-x11 To unsubscribe, send any mail to "[email protected]"
