It seems to be the very same issue! I don't know if it's something in composite or is just that I am using opengl graphic: I don't use any game or graphical apps so I don't know if this issue occurs even without beryl, but while using some 3d intensive app. Did you try this?

I have used my computer for about 12 hours without any issue when I tested it without ipw3945, but did not test it more as I wanted to try shaundennie's suggestion and was hoping to get a better trace to help the devs to fix this.

I have blacklisted ipw3945 now and I will try to see how much uptime I can do without a crash.

Same here. I am tickless now.

I have found this in my dmesg:

ACPI: BIOS bug: multiple APIC/MADT found, using 0
ACPI: If "acpi_apic_instance=2" works better, notify linux-acpi@vger.kernel.org

this problem started when I updated my BIOS to solve the freezing X with moving cursor issue, maybe it's a sort of bug in the HP BIOS which is exposed by a combination of NVIDIA and ipw3945 drivers...

I will post here again if I find out something.
