A problem with the VirtualBox kernel module vboxdrv.ko has been bisected to
commit 2ecd9d29abb1 "sched, preempt_notifier: separate notifier registration
from static_key inc/dec". The affected kernels crash is various ways. The most
instructive includes a warning issued at kernel/sched/core.c:2342 in
prempt_notifier_register() for "registering prempt_notifier while notifiers
disabled" The call from vboxdrv is as follows:
/*
* Register the callback.
*/
preempt_disable();
pThis->fEnabled = true;
preempt_notifier_register(&pThis->LnxPreemptNotifier);
preempt_enable();
As I have no reason to suspect the kernel after this patch, I would like some
suggestions regarding the best method to patch/fix the VirtualBox code.
Thanks,
Larry
