I've tried memtest86+ with two passes and no memory related errors are
recieved.

I booted with above line but nothing changed. Then I booted in to my old
kernel (dated January 29, 2009) with new userland, but there also I
received that segfault, so I guess this is something userspace related.

BtW, I also tried compiling deskutils/google-gadgets 0.10.5[1] port and
there too I've received similar segfault.

I'm attaching the output of 'dmesg' booted in verbose logging mode in both
the kernels. The boot.new.log contains output from booting in new
kernel, whereas boot.old.log contains output from booting in old
kernel.
