After updating to latest kernel and nvidia from livna there is some sort of kernel corruption - triggered by running graphics (bzflag e.g). I am filing this with linux-bugs@xxxxxxxxxx as well. Packages: kernel-smp-2.6.15-1.1830_FC4 nvidia-glx-1.0.8178-0.lvn.1.4 kernel-module-nvidia-2.6.15-1.1830_FC4smp-1.0.8178-0.lvn.1.4 Problem: Feb 4 10:54:47 A kernel: Bad page state at free_hot_cold_page (in process 'b zflag', page c13861e4) Feb 4 10:54:47 A kernel: flags:0x80000400 mapping:00000000 mapcount:0 count: 0 (Tainted: P ) Feb 4 10:54:47 A kernel: Backtrace: Feb 4 10:54:47 A kernel: [<c014d91e>] bad_page+0x8c/0xc3 [<c014e21c>] f ree_hot_cold_page+0x3a/0x126 Feb 4 10:54:47 A kernel: [<f9324f53>] nv_vm_free_pages+0xc2/0x119 [nvidia] [<f9321874>] nv_kern_vma_release+0x7d/0x98 [nvidia] Feb 4 10:54:47 A kernel: [<c015bc6e>] remove_vma+0x28/0x45 [<c015dd40>] exit_mmap+0xb8/0x100 Feb 4 10:54:47 A kernel: [<c0122c1a>] mmput+0x20/0x97 [<c0127b9b>] do_e xit+0x100/0x400 Feb 4 10:54:47 A kernel: [<c01084cd>] do_syscall_trace+0x1ac/0x1c4 [<c0 127ef0>] do_group_exit+0x29/0x90 Feb 4 10:54:47 A kernel: [<c0104035>] syscall_call+0x7/0xb Feb 4 10:54:47 A kernel: Trying to fix it up, but a reboot is needed
