Hi!

As kernel 3.1.0 was released I decided to switch from legacy IDE drivers to
the new ones, thus activating CONFIG_PATA_VIA=y on my config and turning off
all the old IDE drivers, those where the only things I touched on my config.

The result was a 1 day uptime and then a total freeze with even the keyboard
not responding and the HD led on all the time.  Then I rebooted the machine
and started to search for problems with pata_via and saw a few people
complaining about hangs on both fedora, ubuntu and red hat but everything
was old (early 2.6.30's) and they had not found the root of the problem,
even though some sugestions said that it was due to HPET but I don't have it
enabled.

Today, after an uptime of almost 15 days I got the second hang, again
everything dead with the keyboard not responding, the screen again showed
normal condition, no kernel messages or anything and again the led was on
all the time, again, I have just rebooted it.

Computer is a PIII 1Ghz with a via based motherboard with this ide chip:

        Kernel driver in use: pata_via

Right now for the first time as I switched to run lspci I got this error:

ata2: lost interrupt (Status 0x50)
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata2.00: cmd ca/00:80:3f:9c:fe/00:00:00:00:00/e0 tag 0 dma 65536 out

ata2: soft resetting link
ata2.00: configured for UDMA/66
ata2.00: device reported invalid CHS sector 0
ata2: EH complete

I had never seen this error before and running a grep on all logs looking for
"lost interrupt" only returned this error, no prior ones.

I'm thinking of this problems as via_pata based because of my changes on the
config, but I really don't know if this is the case or if the hardware is
starting to fail, so maybe the best thing to do for now is to go back to the
old IDE drivers and seek high uptimes there and if everything is ok then go
back to try to debug this, as we don't have much info right now.

I'm waiting for comments on what to do with this.

Regards...
