描述

Have several "WARNING" and "BUG" from debug Linux kernel on Fedora 34:

WARNING: CPU: 3 PID: 5680 at kernel/smp.c:874 smp_call_function_many_cond+0x1c7/0x3c0
WARNING: CPU: 3 PID: 6837 at arch/x86/include/asm/kfence.h:44 kfence_unprotect+0x2a/0x90
WARNING: CPU: 3 PID: 6837 at mm/kfence/core.c:135 kfence_unprotect+0x2c/0x90
BUG: kernel NULL pointer dereference, address: 0000000000000018
BUG: sleeping function called from invalid context at include/linux/percpu-rwsem.h:49

Linux kernel is installed from Fedora repos and vbox modules built locally by akmods package.
First warning (smp_call_function_many_cond) occurs at vboxdrv module load.
Rest of errors occur while starting VM -- it does not start after this, hanging on "Starting virtual machine..."
Attaching screenshot and dmesg.

When trying same version of non-debug kernel (from main Fedora repo) and prebuilt vbox modules (from rpmfusion repo) -- there are no such errors and VM starts fine.

Package versions:

kernel-debug-5.13.9-200.fc34.x86_64
akmods-0.5.6-27.fc34.noarch
akmod-VirtualBox-6.1.26-1.fc34.x86_64
VirtualBox-kmodsrc-6.1.26-2.fc34.noarch
VirtualBox-server-6.1.26-2.fc34.x86_64
VirtualBox-6.1.26-2.fc34.x86_64

setting CONFIG_DEBUG_KERNEL to NO in homebrewed 5.19 kernels fixes the crash too more to read: see ticket #21046
