Has there been any progress on this.
I still have the same problem on both kernel 4.15 and 5.4.
I still have to modify logrotate to limit logging or more recently I
have tried stopping the logging of any errors which was not as simple as
I expected as rsyslog uses socket activation under
I have the same flooding of /var/log/syslog about every 200 msecs with:

Oct 27 21:17:02 helios kernel: [11807.497617] ACPI Error: Needed
I can confirm that the full procedure covered in #1 and #5 has worked
for me once I added one addition change. I found a file in
/etc/modprobe.d with the line "alias nvidia off" which prevented
bumblebee from loading the nvidia module. It was in /etc/modprobe.d
//blacklist-nvidia.conf which I
I can also confirm that the 3.19.0.49-generic kernel solves the problem
for me.

I also have a similar problem which does Not seem to be solved by the
patched kernel although the perf report looks very similar and plugging

there is an existing one with all the background. In my opinion what is

How can a confirmed bug affecting so many people for so long be suddenly
changed in importance to Wishlist? It affects everyone using Wine and
makes it near impossible for those with two Wine programs open. I would
vote for Important for all using Wine.

it has to be a BIOS issue of
some sort. Maybe its the overtemp trip in the CPU which is to sensitive, but
as it only occurs in BIOS mode seems this could be changed somehow by a change
