Hi,
the kernel is vanilla except reiser4-for-2.6.25 is patched in.
On thursday I created a raid 1 on my computer.
While the two disks were syncing I went shopping. Screen was blanked while I
was away.When I came back, I got this:

[ 1841.983613] Fixing recursive fault but reboot is needed!
today I started a big emerge -u world and went away. This time in X with
fglrx, so the kernel is tainted. Screen went into standby then off, when it
woke up konsole from kde4.1 misbehaved, and I found this:

I haven't had any problems with 2.6.26-rcX, or 2.6.26.1
Complete dmesg after a clean boot is attached.
I haven't got any of this without screen blanking/dpms standby/dpms off.
