[14e4:4315] Fatal DMA errors on Dell Vostro 1310 (Celeron M540)

(resending this message, as first one has been lost somewhere)

Hi.

I have a Dell Vostro 1310 notebook with Debian Squeeze on board. It have
a Celeron M540 in it, so, it is definitely not an Atom case, and that's
why I decided to send this message.

My experience with drivers and kernels:
With 2.6.30 and earlier wl worked fine.
With 2.6.32-trunk-? wl worked fine, b43 fired dma errors pretty quickly
after start (working time was from 5 secs to 15-30 mins).
With 2.6.32-3 wl has stopped working. It builds fine and shows no
errors, but does not work. Then I tried b43, and got similar results
to -trunk version.
With 2.6.33-2 from experimental b43 works much better - working period
is usually more than five hours, it happily survives s2ram and s2disk.
Right now I am running 2.6.34-rc2-wl (git snapshot from 28th March), it
works as far as I can tell the same as 2.6.33-2 - at least it already
fired dma errors twice (except that it automatically switches to pio
mode).

PIO mode is unacceptably slow - web-traffic speed is about 300kbps,
and when I'm trying to rsync something from nfs, mounted over wi-fi,
all the system gets slowed down, and 100% of processor time is consumed
by a kernel process irq/19-b43 (as shown by htop).

Can I provide any additional info to help solve this problem?

P.S. I also have access to Lenovo G450 with the same (14e4:4315 rev 01)
wireless card, but that worked fine without any glitches on 2.6.32-3 (to
test I copied 7Gb of traffic - all went fine, and during two days I have
not experienced any errors with it (it is not mine notebook, and it's
owner does not use wi-fi, so, there's no extensive testing for that
matter available).
P.P.S. On 2.6.33 and 2.6.34 I have not tested wl, as there's no debian
infrastructure to build broadcom-sta for that kernel versions yet.

System info:

Bios is A15 (latest version from vendor), IIRC, it is a Phoenix one.

Operating system architecture is 32-bit, although processor, seemingly
should support 64-bit.

Firmware version is 4.178.10.4.

The system have 1Gb of RAM.
