Re: [PATCH] b43: Increase number of RX DMA slots

2013/2/18 Larry Finger [off-list ref]:

Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G
were due to overflow of the RX DMA ring buffer, which was created with 64
slots. That finding reminded me that I was seeing similar crashed on a netbook,
which also has a relatively slow processor. After increasing the number of
slots to 128, runs on the netbook that previously failed now worked; however,
I found that 109 slots had been used in one test. For that reason, the number
of slots is being increased to 256.

So probably ideal solution is to use 128 *and* fix the driver's
failing on overflow ;)

Did you try it on some old device? Just for sure firmware&DMA will
handle it correctly.
