[Bug 1848445]

2020-01-07 Thread rui.zhang
it is really rare to see a system running with acpi=off.
May I know why acpi=off is used in the first place?

for this particular issue, please confirm if problem still exists with
acpi_osi=!.

you can attach the out of "grep . /sys/class/thermal/thermal*/*"

/sys/class/thermal/thermal*/temp shows the current temperature of each
thermal zone.

[Bug 1806682]

2019-01-10 Thread rui.zhang
According to the acpidump, there is no _PSL control method, which is mandatory 
for a passive trip point.
So, this is a BIOS bug to me, and there is no way to fix it in Linux kernel.

Bug closed.

BTW, if you're running into a real overheating issue on this machine, I
think you can set CONFIG_INT340X_THERMAL and use the int340x thermal
drivers plus userspace thermal daemon for thermal control.

I can not access this page.
But if you can confirm the problem still exists in 4.19-rc1, and the revert 
indeed fixes it, I will send the revert patch out.

yes. there is indeed an interrupt storm, and this could increase the
power consumption easily.

It is very likely that the I2C bus is not powered off cleanly during
reboot.

so, when you say normal boot, you mean a cold boot, say, in 4.17.0
kernel, shutdown the machine, and then power on the machine manually to
boot into 4.9.3 kernel, right?

If this is true, we are still able to confirm the good and bad kernel,
by do cold boot every time, right?

As this seems to be a driver issue, reassign to I2C experts anyway.

this is important, please attach the output of "turbostat --debug" and
"powertop --html=foo" for both good and bad case, in 4.9.3 kernel.

As the problem can also be reproduced on 4.9.3, remove the regression
flag for now.
