[PNP] rare BSOD 0x139 during 2nd stage device installation

VBox 4.3.12 + 1500MB RAM spent to VM

I had a BSOD during 2nd stage device initialization using
0.4.13-RC-7-g67211fa_BSOD_2ndStage.png
0.4.13-RC-7-g67211fa_BSOD_2ndStage.log
that I have never seen before during the last years.

When I reinstalled that exact same iso again, it did not happen again.
Eventually it's related to timing or caused by some memory corruption?

Please notice, that the resource conflict
(ntoskrnl/io/pnpmgr/pnpres.c:615) Resource conflict: IRQ (0x4 0x4 vs. 0x4 0x4)
was always logged for years since I use ros and VBox, It never led to a BSOD though.
