[Drew Abbott]

Hello,

I have been troubleshooting problems with the vanilla and lts linux kernels
for a couple of weeks now and saw this mailing list in MAINTAINERS for
problems with mm.h; apologies if this is the wrong place to ask. I have
been experiencing many freezes and panics with this hardware:
https://pcpartpicker.com/user/Abbott/saved/#view=wXdgt6
Originally[0], many of the traces referred to cpu idling funcs that seem to
be addressed already[1][2], but now all of the traces refer to problems
with paging[3][4][5][6]. I normally mount a mergerfs filesystem at boot
that I thought was causing the panics[7], but I have since removed that
entry from fstab and can still see paging bugs without that fs (or any
other FUSE fs) mounted[7].
What can I do to keep my computer from freezing and panicking?

Thank you,
Drew Abbott

MAINTAINERS file says:

MEMORY MANAGEMENT
M:	Andrew Morton <akpm@linux-foundation.org>
L:	linux-mm@kvack.org
S:	Maintained
W:	http://www.linux-mm.org
T:	quilt https://ozlabs.org/~akpm/mmotm/

F:	include/linux/mm.h
F:	include/linux/mmzone.h
F:	include/linux/pagewalk.h
F:	include/linux/vmalloc.h
F:	mm/

so linux-mm@kvack.org would be better IMO.

SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data at line 1 column 16 of the JSON data

That was on Firefox.
Opera can display it successfully.

I'll put my log up on another paste host, thanks again.
