linux 2.6.12 instability

hippo, I'm starting a new thread to keep track of this... I think 2.6.12 looks better than .16 - it hasn't failed on me yet. the patches you gave me were a bit messy though, I think may...

that's a good patch system, i didn't know you had set it up that way - could i get the patch set for .14 and .16?

when i noticed the dd issue, i was using a avalon system with pipelining enabled. when i addeda dma component to the system, it locked everything up when i would try and access certain registers. it's definitely an avalon bug, and i have my fae looking into it. anyway, i'm not using pipelining now, so i'm seeing if it makes a difference with this issue.

You need to be very careful with DMA, the original 2.6.11 port of Microtronix did not handle DMA cache. And it is very important for PCI. Anyways, I fix them and my PCI is working well.

Pipelineing is quite new. I had asked for it long ago. But it is still not usable for me up to now.

Those patches are too big to post here. I have only 1MB quota here. Please give me an upload point to my private mail. I will prepare them when I have time.
