Based on patch by James D. Nurmi:
I've got some code very dependant on nfnetlink_queue, and turned up a
large number of warns coming from skb_trim. While it's quite possibly
my code, having not seen it on older kernels made me a bit suspect.
Anyhow, based on some googling I turned up this thread:
http://lkml.org/lkml/2006/8/13/56
And believe the issue to be related, so attached is a small patch to

The windfarm code, in it's current incarnation, uses request_module() to
load the various submodules it needs for a given platform so that only
the main platform control module needs to be modprobed. However, it was
missing various bits. This fixes it. In the future, we'll use some
hotplug mecanisms to try to get all of this auto-loaded on the platforms
where it matters but that isn't ready yet.

I wanted to add some BUG checks to scsi_prep_fn to make sure no one
sends us a non-sg command, but this function is a horrible mess.
So I decided to detangle the function and document what the valid
cases are. While doing that I found that REQ_TYPE_SPECIAL commands
aren't used by the SCSI layer anymore and we can get rid of the code
handling them.
The new structure of scsi_prep_fn is:
(1) check if we're allowed to send this command
(2) big switch on cmd_type. For the two valid types call into
a function to set the command up, else error
(3) code to handle error cases
Because FS and BLOCK_PC commands are handled entirely separate after
the patch this introduces a tiny amount of code duplication. This
improves readabiulity though and will help to avoid the bidi command
overhead for FS commands so it's a good thing.
I've tested this on both sata and mptsas.

When called to do a transfer that has a start offset within the cache
line which is uneven between source and destination and a length which
terminates the source of the copy exactly on a cache line, one extra
line gets copied into a temporary buffer. This is normally not an issue
since the buffer is a kernel buffer and only the requested information
gets copied into the user buffer.
The problem arises when the source ends at the very last physical page
of memory. That last cache line does not exist and results in the SHUB
chip raising an MCA.

Komuro reports that ISA interrupts do not work after a disable_irq(),
causing some PCMCIA drivers to not work, with messages like
eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx
eth0: found link beat
eth0: autonegotiation complete: 100baseT-FD selected
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
...
Linus Torvalds <torvalds@osdl.org> said:
"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic
_before_ the mask logic, so if a edge happens _while_ the device is
masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt).
So when you "mask" an edge-triggered IRQ, you can't really mask it at all,
because if you did that, you'd lose it forever if the IRQ comes in while
you masked it. Instead, we're supposed to leave it active, and set a flag,
and IF the IRQ comes in, we just remember it, and mask it at that point
instead, and then on unmasking, we have to replay it by sending a
self-IPI."
This trivial patch solves the problem.
