#3981 fixed vbi module panic on opensolaris kernel build 114 and newer => Fixed in SVN Juergen Keil
Description

With the putback for bug 6565817 "sigwait can't wait for SIGTSTP" the Solaris kernel data structure kthread_t was modified. http://bugs.opensolaris.org/view_bug.do?bug_id=6565817

The vbi kernel module distributed with VirtualBox 2.2.2 seems to access data in kthread_t using the old offsets, so that it panics when we run on a build 114 (or newer) kernel. To reproduce the problem, try to start a virtualbox guest on an opensolaris build 114 (or newer) host.

Panic information:

> ::status
debugging crash dump vmcore.0 (32-bit) from max
operating system: 5.11 snv_115_jk (i86pc)
panic message:
BAD TRAP: type=e (#pf Page fault) rp=b5104bf4 addr=4 occurred in
module "vbi" due to a NULL pointer dereference
dump content: kernel pages only
