Description Jan Beich freebsd_committer 2019-11-26 17:10:05 UTC
Affects at least armv6, armv7 and aarch64. However, aarch64 packages are built on real hardware, so pkg-fallout@ is silent.

(In reply to Jan Beich from comment #0)

Thanks for the report! It seems we still have some threading issues to work out in bsd-user. =-(

We're focusing on getting our branch of qemu-user-static rebased to qemu-3.1 pushed out the door so that riscv64 people can make progress on ports building, then this is likely our highest priority after that.
Comment 2 Dan Nelson 2019-12-21 16:34:07 UTC
Also hangs on mips, so it's not architecture-specific.  The process that hangs in my case is gmake, and that doesn't use threads (unless you mean that qemu-user-static uses threads internally).  A stack trace of the process that qemu-*-static is running would probably be useful, but I don't know how to generate that.
