Hi @kaihengfeng

Yes, mitigations=off works on my ASUS pentium M (banias) machine with with ATI Mobility Radeon graphics, for all of 4.15.0-48, 4.15.0-50 and 4.15.0-51.
At the moment, unable to check on the HP6710b laptop this bug was originally reported on, as I've loaned it to my brother.

Q: Were you suggesting mitigations=off as a solution (given the theoretical security vulnerabilities of spectre/meltdown), or just as a troubleshooting/diagnostic measure?

I'm wondering if I would be better off sticking to 4.15.0-47 with mitigations on, or allowing other kernel patches with mitigations=off? Or 64bit linux may be the better solution, where possible/practicable.

Thanks for suggesting the mitigations workaround!!!
