Description

Hello,

from time to time, I experience alignment traps on my Freerunner, involving various binaries. I'm not sure whether this is a result of a bug in the software which is trapping, a bug in the kernel I'm running (2.6.29-GTA02_stable-t-mokodev) or a hardware defect. This time, Xglamo crashed, but the remaining system remained stable.

root@om-gta02:~# dmesg | grep Xglamo
[ 5116.140000] Alignment trap: Xglamo (1510) PC=0x40283fc4 Instr=0xe5846008 Address=0xfc610007 FSR 0x803
root@om-gta02:~# md5sum $(which Xglamo)
3ddb5f186f92e6a6f56eb923732bf7dc /usr/bin/Xglamo
root@om-gta02:~#

I have not yet found a reliable way to reproduce this type of bug.
I know that it may be hard to analyze this bug (given this little information), but maybe other people who have the same problem gravitate to this ticket and can contribute useful information.
