Reference Mail: kernel: xhci_hcd 0000:00:14.0: ERROR unknown event
type 37 - Kernel 4.19.13
I had a leak somewhere and I was directed to look into SUnreclaim
which was 5.5 GB after an uptime of a little over 1 month on an 8 GB
system. kmalloc-2048 was a problem.
I just had enough and needed to find out the cause for my lagging system.
I finally upgraded from 4.18.16 to 4.19.13 and enabled kmemleak to
hunt for the culprit. I don't think a day had elapsed before kmemleak
crashed and disabled itself.
I'm thinking my USB TV tuner or Intel USB controller may have been too
much for kmemleak given it occured in the middle of one of the
"unknown event type 37" log spams.
It was unrelated to my USB issue. It happened again after I rebooted
within 4 hours of uptime.
This time there were 2 traces, one right after the other and included
another line number.

Under memory pressure, kmemleak may fail to allocate memory. See this
patch for an attempt to slightly improve things but it's not a proper
solution:

I'm not all that sure it was memory related based on my Sun, 6 Jan
2019 13:17:04 -0600 post.
You'll see the log entries at 3AM, and based on earlier entries I
likely went to sleep around 1AM which would mean any memory intense
applications (eg. virtual machine) would've been closed out.
I have 8GB RAM in my desktop.

One more thought that may be nothing, but when kmemleak crashed,
SUnreclaim was at 932552 kB, and after reclaimed/cleared 299840 kB.
There weren't any performance issues like when I had a leak of 5.5 gB
in the 4.18 kernel.
