>Description:
On Feb 25, the NetBSD Test Fixture reported a new failure of the
rump/rumpkern/t_vm:uvmwait test case to current-users. The problem
still exists as of Feb 28 (source 2020.02.28.22.14.10), and also
affects real hardware as seen in:
http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2020/2020.02.28.22.14.10/test.html#rump_rumpkern_t_vm_uvmwait
A copy of the automated report follows, with the commit list trimmed
of some commits that have since been eliminated by bisection. Further
bisection is nontrivial as the system was failing to boot during the
entire time period covering the trimmed-down list of commits.
Subject: Automated report: NetBSD-current/i386 test failure
Date: Tue, 25 Feb 2020 01:55:29 +0000 (UTC)
This is an automatically generated notice of a new failure of the
NetBSD test suite.
The newly failing test case is:
rump/rumpkern/t_vm:uvmwait
The above test failed in each of the last 3 test runs, and passed in
at least 27 consecutive runs before that.
The following commits were made between the last successful test and
the failed test:
