Description Jesse Barnes 2015-08-03 23:16:19 UTC
Happens with current kernels as well as the 3.13 kernel from Linux Mint 17.  Still trying to find a working version (this used to be my everyday machine, so I know it worked a long time ago at least).

System Information

        Version: ThinkPad X200s

I think I have an affected machine.  It's not at all easy for me to test things on that machine, though.
Comment 2 Aaron Lu 2015-08-19 09:27:26 UTC
OK, please find out the working kernel and perhaps git bisect the offending commit.

Most of the time, the failure is not with device drivers, but still, it may be worth a try as the document says:

Comment 3 Aaron Lu 2015-08-28 02:58:29 UTC
Clear the regression flag till a working kernel version is found.
BTW, it should be 4.2-rc4 instead of 4.3-rc4 at this moment.
Comment 4 Aaron Lu 2015-09-11 03:13:53 UTC
Any update on the finding of a working version?
Comment 5 Aaron Lu 2015-09-11 03:14:19 UTC
Also, did you try the basic-pm-debugging document?
Comment 6 Jesse Barnes 2015-09-11 16:48:20 UTC
Yes, that was the first thing I tried, all the options except the actual suspend work fine.

An no I haven't found a working version yet (need to try something really old I guess).
