Comment # 35 on bug 76490 from 
I have to do this:

{ PCI_VENDOR_ID_ATI, 0x6810, 0x174b, 0xe271, 85000, 90000 },

This is with a Sapphire Radeon R9 270X 2GB GDDR5.

A higher value for either sclk or mclk results in an instant freeze as soon as
the radeon kernel module gets loaded.
I'm running linux 4.1 from airlied drm-fixes branch.

I'm quite annoyed by this, because of 3 reasons:

1) I bought this card, because my old card had this PM bug and this didn't look
like it would be fixed any time soon:
https://bugzilla.kernel.org/show_bug.cgi?id=60523

2) With the settings above the performance of the card is actually *worse* than
the old card (+ additional graphical glitches...)

3) This card works fine with any sclk/mclk combination with the same vddc
(1238mV) in windows and I can overclock there!

I'm also wondering why I get a different VBIOS size if I get the bios in
windows (gpu-z) and linux. Is it because different firmware gets loaded? The
(working) vbios under windows is twice as large as the linux one (see
attachments).
