net,runtime: apparent deadlock in (*net.conn).Close and runtime.netpollblock on arm64 platforms [1.17 backport] #49010
Description
@prattmic requested issue #48925 to be considered for backport to the next 1.17 minor release.
@LaPingvino give the new version a try, though it sounds like you may be having a different issue. Logs would definitely help.
@gopherbot please backport to 1.17 and 1.16. This is a pre-existing issue with no workaround, and causing flakes on trybots.
