Bug#1055881: virtualbox-dkms: Linux 6.7-rc1 throws "invalid opcode" during module loading
retitle 1055881 Linux 6.7-rc1 / Linux 6.6.1 UBSan errors forwarded 1055881 https://www.virtualbox.org/ticket/21877 thanks I found the "invalid opcode" was caused by CONFIG_UBSAN_TRAP=y, that was set by the hardening.config from linux 6.7-rc1. Using the same options I can reproduce the bug on 6.6.1, too. This is also reported upstream as https://www.virtualbox.org/ticket/21877 Changing CONFIG_UBSAN_TRAP to no shows these errors in the log (see attachment. Sorry for the wrong noise, but I suggest to keep this bug open, since there is no similar bug reported. Ingo -- const_cast(Λ) [ 17.127943] vboxdrv: loading out-of-tree module taints kernel.
