Hi there!
After recent kernel update I can't load virtualbox modules. Right now I have 6.6.57-gentoo-dist kernel installed. After updating to 6.6.57 I rebuilt virtualbox-modules package, but I can't load it:
Code:
modprobe vboxdrv
modprobe: ERROR: could not insert 'vboxdrv': Exec format error


Virtualbox and virtualbox-modules are both 7.0.20

Code:
modinfo vboxdrv
filename:       /lib/modules/6.6.57-gentoo-dist/misc/vboxdrv.ko
version:        7.0.20 r163906 (0x00330004)
license:        GPL
description:    Oracle VM VirtualBox Support Driver
author:         Oracle and/or its affiliates
srcversion:     9CBC44140E50A5E89770210
depends:       
retpoline:      Y
name:           vboxdrv
vermagic:       6.6.57-gentoo-dist SMP preempt mod_unload
parm:           disabled:Disable automatic module loading (int)
parm:           force_async_tsc:force the asynchronous TSC mode (int)

Any idea on what's going on/

That error can be caused by something being built for an architecture different to the one it actually ends up running on. Did you rebuild on a host other than the one on which you're trying to run VBox?

Updated to gentoo-kernel-bin-6.6.58r2 and rebuilt virtualbox-modules-7.0.20 - still can't load vboxdrv:
Code:
# modprobe vboxdrv
modprobe: ERROR: could not insert 'vboxdrv': Exec format error

i'm wondering whether the output of `dmesg | grep vbox` might offer a lead?
