[Bug 640154] Re: BUG: unable to handle kernel NULL pointer dereference in ips_adjust in intel_ips on Sony VPC-B11KGX

[Derek]

No shock, but blacklisting intel_ips avoids the oops.
No sound still, so that's presumably unrelated.

I'm skeptical the IPS was doing anything useful due to:
[    6.873860] intel ips 0000:00:1f.6: Warning: CPU TDP doesn't match expected value (found 25, expected 35)
and
[    6.874061] intel ips 0000:00:1f.6: failed to get i915 symbols, graphics turbo disabled
