I'm experiencing a similar problem but i dont use suspend. What happens
is that after some time of being running, my laptop just freezes for
about 10 seconds, then gets back to normal, then 1 or 2 minutes after it
freezes completely. The first time it happened i tought it was an
hardware problem but when i looked at syslog, i found those hdc
interrupt errors (my combo drive).
If i disable hal, everything's ok. If i use it, well, it happens.
As i read here, i tried to remove ohci1394, but with no luck, it happened
again. Now i tried disabling DMA on my combo drive and i'm waiting for results.
I'm running Dapper Drake as well, and this already happened in Breezy,
but at the time i found a bug report somewhere else which talked about
kernel bugs that would probably be solved on 2.6.15 so i waited. Looks
like those bugs aren't gone.
My laptop is an Airis DIamond 630 (i know...weird), a Pentium IV 2.80ghz on an
Intel based motherboard. Here's an lspci:

Here's the interrupt errors from syslog:

I'll try updating to 2.6.16 if disabling dma does nothing for me.
