I tested 14.04 LTS, 16.04 LTS, 16.10 (with both kernels - ordinary and
mainline) - the bug exists only on 12.04 LTS with 3.2 kernel. So the bug
is 'Confirmed' and I added 'kernel-fixed-upstream' tag.
Thank you, Joseph!

GEN6_RP_INTERRUPT_LIMITS" messages in syslog
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have two error messages on my Asustek UX32A laptop.
They are:
Jul 12 12:23:23 norbert-flash kernel: [ 21.384213] [drm:gen6_sanitize_pm]
*ERROR* Power management discrepancy: GEN6_RP_INTERRUPT_LIMITS expected
18000000, was 12060000
Jul 12 15:23:43 norbert-flash kernel: [ 41.084122] [drm:gen6_sanitize_pm]
*ERROR* Power management discrepancy: GEN6_RP_INTERRUPT_LIMITS expected
18070000, was 18000000
It seems that 3.2 kernel is not compatible with my CPU/GPU (Intel
i7-3537U).
