Hi Guys,

I really can't remember a crashreport until now in ver. 2.7.2. I've got the full CR. too. Page Fault.... could it be upcoming RAM Problem/s (hardware)????

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address	= 0xf8
fault code		= supervisor read data, page not present

Read Crash Report - Fatal trap 12: page fault while in kernel mode (lsof) first to get a general idea of the issue.

From what you've shown, I see a page fault (that's Intel's trap 12).
In the kernel space (the upper 0xfffffff..... part of memory).
The 'name' of the part of the kernel where it happened is 'usbus0' (driver) so the issue arrived when dealing with USB traffic (?).

The post I mentioned above shows more details, like the called function stack.
That said, "trap 12" can't be finger pointed easily.

General observations are ;
Maybe you are using to modern hardware with software that is to old ?
Or the other way around ?
I mean 2.7.2 was good, but pretty ancient by now.

Hi Gertjan,

The HW is a Vault FW2B, nowadays it's pretty old too :-[
But it works prefectly. I dont use the USB Ports.

What does the backtrace in the crash report show?
