https://bugs.winehq.org/show_bug.cgi?id=52846 --- Comment #2 from Hans Leidekker <hans(a)meelstraat.net> --- (In reply to Louis Lenders from comment #1) It performs the same query simultaneously from 2 threads, which involves an ioctl to mountmgr: 0144:trace:wbemprox:wbem_services_ExecQuery 0000000000F03430, L"WQL", L"SELECT Antecedent, Dependent from Win32_LogicalDiskToPartition", 0x10, 000000000000000 0, 000000001E1DEF08 ... 0160:trace:wbemprox:wbem_services_ExecQuery 0000000026767CC0, L"WQL", L"SELECT Antecedent,Dependent FROM win32_logicaldisktopartition", 0x10, 0000000000000000 , 0000000032DFEBE8 Unfortunately the backtraces aren't very useful. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
