Hello Austin,

--- quote ---
Adding a stub gets it a bit further:
fixme:ntoskrnl:__regs_KfRaiseIrql (2) stub!
fixme:ntoskrnl:IoStartNextPacket (0x1139c8 1) stub
fixme:ntoskrnl:__regs_KfLowerIrql (0) stub!
fixme:ntoskrnl:KeWaitForSingleObject stub: 0x110ea8, 0, 0, 1, (nil)
fixme:ntoskrnl:KeWaitForSingleObject stub: 0x1129c8, 0, 0, 1, (nil)
fixme:ntoskrnl:KeReleaseMutex stub: 0x1129c8, 0
err:int:emulate_instruction Unsupported DR register, eip+2 is c0
wine: Unhandled privileged instruction at address 0x54490d (thread 0026),
starting debugger...

with a dialog saying:
Code: -7
--- quote ---

that's another Wine shortcoming, deserving its own bug.
That crash is due to incomplete "mov drX, eax" (AT&T syntax) support.
Currently only DR1 and DR7 are handled.

Regards
