[HP Pavilion 11-n010dx x360 PC] hp_accel causes freeze on load

[Weldon Goree]

On my HP Pavilion x360 if hp_accel is not blacklisted it will cause a freeze on load during the boot process. The attached unified.log is when hp_accel is blacklisted.

WORKAROUND: Blacklist hp_accel.

Sorry some of those came twice. Anyways, I found the dw_dmac* bug that also hits this model:

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Same problem (and workaround) on 3.18-rc5-vivid (and 3.18-rc2-utopic).
