Newbie: 1st LinuxCNC install, crashes when I run it

It is my 1st install of LinuxCNC. I just downloaded it and installed fresh. Pretty clueless what to do, so..
I ran LinuxCNC config picker, selected something like stepper sim_inch.
Got some black screen, which looks like crash dump. After reboot I found it in syslog.
Help?!
Thanks for your help in advance

Can you please attach the linuxcnc error log? Look under "debug info" for errors.

Where do I find "linuxcnc error log"?

When you start Linuxcnc, if there is an error it will show a screen with informations about what went wrong. Thers you have a button to copy it to clipboard.
Or you can start Linuxcnc from the terminal and see what is going on.

There was no button, just black text screen. I got a picture of it. Could not do much more

That looks like a computer problem. Did you check the downloaded image with md5sum?
I would advice to check the image and do a new install, or even beter make a bootable usb with that image and start it from usb so you can test it.
That might just work.

That's a linux kernel oops (crash)

This may indicate bad or incompatible hardware of some kind

What hardware is this running on?

Have you run memtest86 to verify the the memory is OK?

So I downloaded and verified ISO image again. Burned it. reinstalled. Same thing
Memtest86 from boot menu passes. It surely takes some loooong time to complete.
Problem still persists.
I have ASUS M4A49GTD PRO/USB3 motherboard with AMD Phenom II CPU.
3GB of memory.
Let me know if there is a command I can use to dump more hardware info.

uname -a
on the machine would let us see if we recognise the kernel, but really that should be right with a liveCD install.

Does the latency test (in the CNC manu) run without crashing? What numbers?

Latency test was failing too. But, I got a break through of sorts.
Was monkeying around BIOS settings. Disabled "ACPI APIC support" which described as "Include ACPI APIC table pointer to RSDT pointer list" (All of that has no meaning to me). And it started to work.
Latency test shows:

	Max Interval (ns)	Max Jitter (ns)
Servo thread (1ms)	1200846	202526
Base thread (25m-s)	215668	190716

Not sure how to read those

When I try to run LinuxCNC Config Picker and select "by interface" / parport / stepper / sim_inch, I get some window show, titled "axis.ngs - AXIS 2.7.0 on LinuxCNC-HAL-STEP-SIM". It also shows some error message in bottom right corner: "RTAPI: ERROR: Unexpected realtime delay on task 1. This Message will only display ones per session. Run the Latency Test and resolve before continuing."
So I'm guessing my latencies are not so good.
