Port lock was not acquired

Post by JamesB »

Since "upgrading" from VirtualBox 4.1.6 to 4.1.8, I am now receiving in Windbg the error message "Port lock was not acquired" on a regular basis.
It seems to be output every second or two. PIIX chipset is set -- ICH makes things even less stable. After a while, I get a crash in ntkrnlmp.exe:

Anyway, I'm going to go "downgrade" to 4.1.6 now. Probably you'll want to investigate this bug.
