Hi there,

I'm having all kinds of odd issues IDE on these VIA chipsets (VIA C3
 mini-itx machines). After a certain amount of time (goes from one 
hour to a month) the harddrive (or the whole ide subsystem?) 
will go nuts with the following messages, which I've finally managed 
to capture through a serial console. The machine doesn't hardlock 
but it's impossible to launch any command or reboot the machine remotely.
I've even tried with "ide0=serialize ide1=serialize",
since I read on this list that these options would cure most of the 
obscure IDE setups, but the problem still persists. 
I've reproduced this problem with all of the 2.4.2[4-8] series 
and also with 2.6.3 (which is the only one I tried some time ago).
I attach the error messages, lspci and lsmod (kernel is 
compiled with CONFIG_BLK_DEV_VIA82CXXX=y).

Since I have about half a dozen of machines that fail this way, I was 
wondering if it is a H/W problem or something else. 
Thanks for any hints on how to debug further this problem.

The drive went for a walk and didn't come back

That could be a whole pile of things (for reference I get 100+ day
uptimes on VIA mini-itx boxes)

1. Overheating
2. Lack of power
3. Some glitch that then triggers the kernel error recovery into
upsetting the drive.

If it reboots back happily then all 3 are quite plausible
