Bug ID: 47873 Summary: kernel32:comm fails randomly Product: Wine Version: 4.17 Hardware: x86 OS: Windows Status: NEW Severity: normal Priority: P2 Component: kernel32 Assignee: wine-bugs@winehq.org Reporter: fgouget@codeweavers.com
kernel32:comm fails randomly on multiple Windows versions:
comm.c:708: Found Com port COM1. Connected devices may disturb results comm.c:859: Test failed: WaitCommEvent failed with a timeout comm.c:870: recovering after WAIT_TIMEOUT... comm.c:880: Test failed: WaitCommEvent error 0 comm.c:881: Test failed: WaitCommEvent: expected EV_TXEMPTY, got 0 comm.c:885: WaitCommEvent for EV_TXEMPTY took 1500 ms (timeout 1500) comm.c:886: Test failed: WaitCommEvent used 1500 ms for waiting
https://test.winehq.org/data/tests/kernel32:comm.html
These failures are random and have been seen on the following TestBot VM4 configurations: wxppro w2003std w7pro64-32 w1064v1507-32 w1064v1607-32 w1064v1607-64 w1064v1709-64 w1064v1607-64 w1064v1809-32 w1064v1809-32 w1064v1809-64 w1064v1809-2scr-32 w1064v1809-fr-64 w1064v1809-ja-32 w1064v1809-ja-64
So it does not depend on the Windows version, bitness of the test, or locale. However it only happens on QEmu VMs: it never happened on the fg-win7u64 VMware VMs or on the real hardware machines, cw-rx460 and cw2-gtx560.
Yet the VMware VMs have two serial COM ports, and, according to dmesg | grep tty, the real hardware machines do have a serial port too.
QEmu bug?

--- Comment #1 from François Gouget fgouget@codeweavers.com --- If the issue is a QEmu bug this may be a duplicate of bug 48108.
