After upgrading from linux 3.7.10-1 to 3.8.4-1 xorg started crashing. The backtraces point to radeon_drv.so I am using a Radeon HD 3600. It is also worth noting that the kernel was booted with radeon.no_wb=1 parameter. Downstream bug, including some backtraces: https://bugs.archlinux.org/task/34563
This is a duplicate of this bug: https://bugs.freedesktop.org/show_bug.cgi?id=61182 It's not a kernel issue, it's a mesa bug with features that are only enabled with 3.8 kernels.
Not a kernel issue follow https://bugs.freedesktop.org/show_bug.cgi?id=61182 for resolution
Are you sure it's the same issue? Because after reverting 35840ab189595b817fa8b1a1df8cc92474a7c38d in mesa I still get crashes.
