100% CPU kworker on SD card insert
From: Piotr Maksymiuk
Date: Sun Mar 20 2016 - 10:22:14 EST
Hello everyone. This is my first bug report, so I took it step by step from https://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html. I tried contacting the driver maintainer for sdhci-pci, since this is where I think the problem originates, but there was no reply, so here I am.
[1.] One line summary of the problem:
100% kworker CPU usage on SD card insert
[2.] Full description of the problem/report:
When i insert a SD card into the SD slot of mu NUC6i5, a kworker uses up 100% of one core. It doesn't matter if the card is mounted or not, and this persists until a reboot. From perf it looks like some ACPI/IRQ stuff. The SD card works fine however.
[3.] Keywords (i.e., modules, networking, kernel):
acpi, sdhci
[4.] Kernel version (from /proc/version):
Linux version 4.5.0-gentoo (root@xxxxxxxxxxx) (gcc version 5.3.0 (Gentoo 5.3.0 p1.0, pie-0.6.5) ) #6 SMP Sun Mar 20 01:41:49 CET 2016
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
There is no oops

problem (if possible)

[7.6.] SCSI information (from /proc/scsi/scsi)
I don't have this for some reason
[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
I'd also like to attach the output of perf, but the file is 3MB, and I don't know how to do this without bloating the mail more than it is. I've left it here however https://dl.dropboxusercontent.com/u/196370/perf.data
[X.] Other notes, patches, fixes, workarounds:
This also happens on 4.4.5. It's a new machine, so I didn't have the chance to run anything earlier.
