[Asus Transformer TF700] brad0112358:
No, the nvidia kernel memory allocation bug is still not fixed. I fired up google maps, did a few zooms, and it crashed the dmesg output (included below) shows that nvhost is still trying to allocate 16 pages at a time which often fails: They fixed it in JB on the TF300. I suspect we will have to wait for that.
