i2c_designware 808622C1:06: punit semaphore timed out, resetting

[Chris Cheney]

kernel crash on boot rendering sdio wifi and bluetooth from operating on Nexbox T9 (Intel x5-z8300), works fine under Windows 10. It happens on both 16.04 and 16.10 with kernel 4.4.0 and on kernel 4.8.0-rc4 on Fedora 25 alpha. The acpi errors don't show up in the 4.8.0 kernel dmesg.

Ubuntu 16.10 output.

I dug around and found upstream kernel bzs related to this issue:

https://bugzilla.kernel.org/show_bug.cgi?id=150481

https://bugzilla.kernel.org/show_bug.cgi?id=155241

[Chris Cheney (ccheney)]

As noted at the link the code is known wrong for CHT but may have further bugs:

https://bugzilla.kernel.org/show_bug.cgi?id=150481#c1

[Brad Baker (bbaker6212-a)]

I could be wrong but this problem looks specific to various cherry-trail Atom devices *and* Kernel 4.4. I have seen this problem fixed on those devices with newer kernels but I don't remember if it was 4.7 or 4.8-RCx

[Marc Neiger (marc-i)]

Still there in Kernel 4.8.9

[Alex (wongv)]

Tried to install Xubuntu on my CherryTrail-based Yepo 737s laptop with same issues as mentioned. Nothing is working - no wifi, nor audio, nor power etc, updated kernel to recent 4.11 and still nothing. I'm upset a bit.

[Chris Cheney (ccheney)]

Alex, you should probably file a new upstream bug about the issue if you can reproduce it on the upstream 4.11 version. I no longer have a Cherry Trail system so can't do it myself.

[Alex (wongv)]

Chris, thanks for reply. I've installed latest (10 may) daily build of kernel and seems it works better, at least I see battery meter and no PUNIT timeouts in dmesg but still no wifi/bt (rtl8723bs) and audio. I will wait for 4.12-rc kernel before filing a bug report.

[Kai-Heng Feng (kaihengfeng)]

r8723bs (sdio wifi driver) is currently in staging tree, so you need to compile Linux kernel yourself to make it work.

[Nicola Lunghi (nicola.lunghi)]

Also affect kernel 4.10.0-40
