Ok, here is my info:
VPC-z2190X, i5-2540, 6GB ram, 128GB SSD dm-raid 0, PMD, 1600x900 screen,
Linux: Ubuntu Natty 11.04 with custom compiled 3.1.0-rc6 x86-64 (no
sparse_irq, vaio patch), gnome 2.32.1

Ethernet timeout: no (although before I moved to rc6 I had compiled the
r8168 driver from realtek. I can't compile it for some reason on rc6 but it
does appear that the r8169 driver works ok.)
Rendering problem: haven't noticed...
Random crash: sometimes. but not really noticeable.

I do have the mtrr errors:

$ dmesg | grep -i mtrr
[    0.000000] MTRR default type: uncachable
[    0.000000] MTRR fixed ranges enabled:
[    0.000000] MTRR variable ranges enabled:
[    2.603613] mtrr: no more MTRRs available
[    2.603618] [drm] MTRR allocation failed.  Graphics performance may
suffer.


$ sudo cat /proc/mttr
cat: /proc/mttr: No such file or directory

And 3d graphics are not that great. Extreme Tux Racer I get like 2 FPS.
Actually now I can't even get glxinfo to show... I wonder what I did...

One other odd thing. I am not sure what I did but when i did an
update-initramfs it kept complaining that I was missing firmware. So I
grabbed the rtl_nic firmware (mdamt-linux-firmware-2.1-0-gbf9f864.tar.gz)
and cp'd it to /lib/firmware/rtl_nic and it seems to be behaving.
