https://bugs.winehq.org/show_bug.cgi?id=44588 Bug ID: 44588 Summary: Multiple kernel drivers need ntoskrnl.exe.KeWaitForMultipleObjects semi-stub (Franson VSerial service 'bizvserialnt.sys') Product: Wine Version: 3.2 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: ntoskrnl Assignee: wine-bugs(a)winehq.org Reporter: focht(a)gmx.net Distribution: --- Hello folks, continuation of bug 32186 copy/pasta of my comments from https://bugs.winehq.org/show_bug.cgi?id=32186#c3 With the stub added, the return value 'STATUS_NOT_IMPLEMENTED' causes an endless looping in driver: --- snip --- ... fixme:ntoskrnl:KeWaitForMultipleObjects (2, 0x64ea4c, 1, 0, 0, 0, (nil), 0x64ea1c): stub fixme:ntoskrnl:KeWaitForMultipleObjects (2, 0x64ea4c, 1, 0, 0, 0, (nil), 0x64ea1c): stub ... <spam> --- snip --- The driver creates a secondary "system thread" using PsCreateSystemThread() which calls KeWaitForMultipleObjects(). Only in case of STATUS_SUCCESS return value the loop is exited and the driver is happy, probably waiting for ioctls from client.
