>Description:

The gxemul-based NetBSD/hpcmips testbed has not successfully completed
an install since gxemul was upgraded from version 0.6.0.1 to 0.6.1.
The currently installed version is gxemul-0.6.1nb2 from pkgsrc.

The other gxemul-based MIPS testbed, for NetBSD/pmax, is working.

Log output from a recent install attempt is at:

  http://releng.netbsd.org/b5reports/hpcmips/2019/2019.05.29.11.27.34/install.log

which shows a timeout after the error message

  warning: LOW reference: vaddr=0x00000000000002f0, exception TLBL, pc=0xffffffff802b7400 <(no symbol)> ]

Other runs appear to time out during set extraction without any error
message, for example:
