Michael, I think this is related to your code (bcm43xx_dma.c). It is
quite possible that the bug isn't in your code, but rather in the
general management of DMA.

Please try latest wireless-2.6 tree. I think it has a bugfix for this.

There is a fix (commit 653d5b55c0125dca97a420b9a5e77fad7adbf3f0) for mac_suspended assertions in the
latest wireless-2.6. If you just want that fix, use the following:

bcm->irq_savedstate = BCM43xx_IRQ_INITIAL;
+ bcm->mac_suspended = 1;
+
/* Noise calculation context */
memset(&bcm->noisecalc, 0, sizeof(bcm->noisecalc));
If this patch is already in your code, and you are still getting the assertions, please let me know.

Thanks. 2.6.18-rc5-mm1 doesn't have this patch. Andrew, could you
pull a current wireless tree into your next mm release?
Cheerio,
Miles
