5.3-BETA4 hangs (ata2 dma problems)

Hi,

experienced 3 hangs in the last 2 weeks regarding dma problems
when having heavy disk i/o.

a) 2 times when trying to copy DVDs from one drive to the other

b) Just a few minutes ago when checking out /usr/ports.
   CVS repository and /usr are on the same disk ad2.

to b). I was under X11/kde3.
I was only able to move the mouse cursor and noticed
dma trouble in the xconsole window.
Sorry I should have written down the messages.
Bad thing is, they didnt make it in the syslog.

What would be the best thing to hunt this down ?
2nd PC on serial console and trying to troubleshoot there ?

I tried to quit X11 via Ctrl-ALT-BS, but then I only hung
somewhere in X11 ...
Ctrl-Alt-Delete was not possible. Via Telnet dunno.
Didnt had a 2nd PC near. I power cycled.

It might be the case that it happens again.

So what would be best to give you better information ?
