I was able to set up my MMIO range with an MTRR of "Write-Protect" using the /proc/mtrr interface:       echo "base=0xd0000000 size=0x08000000 type=write-protect" >/proc/mtrrand "cat /proc/mtrr" confirmed that this set up a Like Show 1 Like (1) Actions 14. Have fun and let us know how it goes. Source

I've also encountered the error when using a SSD. My interpretation is that Linux does not think I should be allowed to make MMIO cached (of any sort), and so it just ignores the request implicit in the "ioremap_cache()" call.   Bandwidth" Top Log in to post comments le g. You may need to do a manual reinstall if roll-back is desired/required (so ensure your current 5.1 ISO is handy too). http://forums.fedoraforum.org/archive/index.php/t-299533.html

Log in to post comments Patrick Fay (Intel) Wed, 05/29/2013 - 05:39 Hello le, I'm not completely sure but I think that PCI-E devices only support uncached/write-combining memory accesses. When you do a write to WB memory, the line sits in the cache for some time until it gets kicked out for some reason. Did you get the error while running memtest?

Only when I set both PAT and MTRR to WB does the kernel crash.

This is a hardware problem, those messages come directly from the processor not the software part, change it, find a firmware, contact the manufacturer. Not a member?

You can even check for those with a camera they show up as bright spots in any camera image because the high energy particles overwhelm the image sensors. There is one set of mappings that can be made to work on at least some x86-64 processors, and it is based on mapping the MMIO space *twice*, with one mapping You might want to create a new topic regarding that in the Hardware subforum, but I expect that replacing the faulty hardware will be your only option (unless you've been twiddling McCalpin, PhD "Dr.

The more generic open source tools are easier to work with, but may not provide enough information to show exactly what's going on.

My guess is that the hardware crashed on this instruction.It is possible to imagine implementations that would convert this transaction to an ordinary 64 Byte IO read, but then some component Re: PSOD CPU hardware error ESXi grasshopper Dec 28, 2013 12:24 PM (in response to pug205) Nice job upgrading so far. We need to execute CFLUSH to invalidate the cache line in WT range once a device memory is modified. Show 14 replies 1.
