Public bug reported: I'm using a 64-bit 11.10 install (just upgraded from 11.04) on a system76 Gazelle Professional 6 laptop (self-install). Ever since I upgraded from 11.04, I'm experiencing sporatic crashes which cause my X session to die, causing me to return the login screen and loose all my work. The xorg log shows a segfault relating to libpthread and libc6. Please note that I am using gdm instead of lightdm to work around a different bug unrelated to this problem.
