BFD: /boot/kernel/kernel: invalid relocation type 37 #82

Closed vishwin closed 6 years ago

vishwin commented 6 years ago

Since around the early r335000s in -CURRENT, I've been getting this panic when our modules are loaded on startup from /etc/rc.conf's kld_list="/boot/modules/drm.ko /boot/modules/i915kms.ko". This occasionally also happens when loaded manually from the shell.

Previous frame identical to this frame (corrupt stack?)
Current language:  auto; currently minimal
(kgdb)

This happens with both drm-next and drm-stable. As usual, built against the same -CURRENT revision. I've also set WITHOUT_BINUTILS_BOOTSTRAP so the kernel does not use bfd at all to no avail.

Also interesting to see improper drm2 interaction here. My hardware is Broadwell which drm2 does not support.

I'm gonna guess some things in base changed sufficiently to fix this crash, so closing for now.
