State-Changed-From-To: open->feedback
State-Changed-By: maya@NetBSD.org
State-Changed-When: Sat, 08 Feb 2020 19:00:09 +0000
State-Changed-Why:
Reading the kernel panic w/o spl not lowered garbage yields:
fpusave_lwp: did not
That was also reported in PR 53017, which is closed (after a reply to PR 53016, which says "does not seem to happen any more")
Are you still having issues?
State-Changed-From-To: feedback->closed
State-Changed-By: maya@NetBSD.org
State-Changed-When: Thu, 07 Jan 2021 15:43:14 +0000
State-Changed-Why:
feedback timeout. Assuming fixed based on my previous question that it is probably fixed.
