I get a failure of 64-bit DMA on a BCM94311MCG rev 02 wireless interface running on x86_64 using an
AMD Turion 64 X2 processor on an HP Pavilion dv2125nr laptop. The error code indicates that the
interface is getting a descriptor read error, even though the descriptor ring and all the DMA
buffers have been checked when allocated. This particular card version is newly supported; however,
it was working correctly on 2.6.24-rc2.
With bisection, the problem commit is as follows:
=================================================
commit 44048d700bcbfaf4bcca6e2e0a73d89d01ec0878
Author: Linus Torvalds <[email protected]>
Date: Mon Nov 12 14:14:44 2007 -0800
Revert "Bias the placement of kernel pages at lower PFNs"
This reverts commit 5adc5be7cd1bcef6bb64f5255d2a33f20a3cf5be.
Alexey Dobriyan reports that it causes huge slowdowns under some loads,
in his case a "mkfs.ext2" on a 30G partition. With the placement bias,
the mkfs took over four minutes, with it reverted it's back to about ten
seconds for Alexey.

===============================================================
I checked that reverting the reversion "fixes" the problem and the device works under a kernel that
git-describe shows as v2.6.24-rc3-190-gae37313.
To me, it seems unlikely that the real problem comes from needing kernel pages to be placed at lower
PFN's, but that there is some other problem with DMA page allocation that is masked (pun intended)
by this scheme of mapping. The problem is easily reproduced, and I am willing to test patches.
