SubjectRE: [lkp-developer] [ACPICA] 174cc7187e: kmsg.ACPI_Error:Mutex[ACPI_MTX_Tables]already_acquired_by_this_thread[#](#/utmutex-#)

Hi, Xiaolong

I noticed the tested version in your the test dmesg: Linux version 4.9.0-rc5
While the commit bisected should be in v4.10-rc1.
Does that mean your test tree doesn't contain some basic lock fixes?

Thanks and best regards
Lv
