Comment 48 for bug 553789

Can we please stop with the "me too"s and useless backtraces already? We already know the bug affects anyone with NVA3+ cards and the backtraces only show the fallout of the fallout of the fallout of the original problem...

Also: if you get a DMA_PUSHER, that's another bug. This bug happens with total silence from the kernel - the card just hangs without telling us why.

Now, a status update. So far, I REd the instruction set and disaassembled a good chunk of that microcode. Sure enough, it pokes PGRAPH and watches for stuff on it. But the code doesn't yet fully make sense to me, and I'm temporarily away from my NVA5 card, so... could someone dump some registers for me?

I need a dump of the registers both before and after the hang. The interesting stuff is in 10axxx range, and ideally I'd want output of "./peek 10a000 1000". However, if the card doesn't like it and hangs or something upon that command, dump registers individually instead by doing "./peek X" for X being 10a008, 10a6fc, 10a4fc, 10a4f4, 10a714, 10a700, 10a704, 10a4dc, 10a690, 10a688.

Repeating that 2 or 3 times may be useful, esp. across different chipsets. But not TOO much, please.
