atl1c: use custom skb allocator
BugLink: http://bugs.launchpad.net/bugs/1221794
[ Upstream commit 7b70176421993866e616f1cbc4d0dd4054f1bf78 ]
We had reports ( https://bugzilla.kernel.org/show_bug.cgi?id=54021 )
that using high order pages for skb allocations is problematic for atl1c
We do not know exactly what the problem is, but we suspect that crossing
4K pages is not well supported by this hardware.
Use a custom allocator, using page allocator and 2K fragments for
optimal stack behavior. We might make this allocator generic
in future kernels.
** Bug watch added: Linux Kernel Bug Tracker #54021

** Changed in: linux (Ubuntu)

Title:
DMA: Out of SW-IOMMU space for xx bytes at device [AR8151 network]
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I just setup Kubuntu Raring on my notebook yesterday and things seem
to work fine except for samba/cifs. Sill using SMBv3 I can't transfer
large files anymore. At about 100MB transfer the kernel log gets
filled with those error messages:
DMA: Out of SW-IOMMU space for xx bytes at device ....
and the network becomes completely unusable. Only solution I have
found was to reboot the system and at shut down, you also keep getting
tons of those errors. However when using SCP or rsync over SSH there
aren't any problems.
My network card: 05:00.0 Ethernet controller: Atheros Communications
Inc. AR8151 v2.0 Gigabit Ethernet (rev c0)
Meanwhile I reverted back to using the 3.5.0-27 kernel from Quantal - that
one has no issues.
