That last comment was from last week - I still had it in my firefox "Restore Session" and had not pressed "Post Comment" yet.
But it just happened again today - it looks like the frequency of this bug is increasing with newer kernel, xorg-server, and xorg-drivers-radeon releases . Here is the info from today's lockup : (gdb) where #0 0x00007f8c7e248337 in ioctl () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007f8c7f52f3a4 in drmIoctl () from /usr/lib/x86_64-linux-gnu/libdrm.so.2 #2 0x00007f8c7f5316bf in drmCommandWriteRead () from /usr/lib/x86_64-linux-gnu/libdrm.so.2 #3 0x00007f8c7a093c83 in ??
