[PATCH] dpt_i2o: don't set DMA_64BIT_MASK [was: Re: [stable] broken dpt_i2o in 2.6.23 (was: ext2 check page: bad entry in directory) (fwd)]

[Miquel van Smoorenburg]

According to Greg KH:
 So, what should be added to 2.6.23-stable then?  And, can I get a real
 changelog entry for it?

This is suitable for both 2.6.23.x and 2.6.24-rc5 :

linux-2.6-dpt_i2o-no-dma64.patch

The dpt_i2o driver can't handle 64 bit DMA addresses, so do not
let it set pci_set_dma_mask(pDev, DMA_64BIT_MASK) .

Actually, this one's already queued:
