As this has now happened twice in the last two weeks, I thought I'd write this up. This morning I came back to my laptop to find it had locked up, even ssh couldn't gain access to the machine. I rebooted the machine and tried to start X. X refused to start, so I looked at the logs where it locked up before I'd even woken up and found the following: May 1 08:37:16 lithium kernel: __ratelimit: 60 callbacks suppressed May 1 08:37:16 lithium kernel: X: page allocation failure. order:1, mode:0x10d0 May 1 08:37:16 lithium kernel: Pid: 11594, comm: X Not tainted 2.6.32-gentoo-r7 #4 May 1 08:37:16 lithium kernel: Call Trace: May 1 08:37:16 lithium kernel: [<c1050e9f>] ? __alloc_pages_nodemask +0x439/0x47b May 1 08:37:16 lithium kernel: [<c106a52e>] ? cache_alloc_refill +0x240/0x411 May 1 08:37:16 lithium kernel: [<c106a765>] ? __kmalloc+0x66/0x9d May 1 08:37:16 lithium kernel: [<f91ee2b5>] ? agp_alloc_page_array +0x22/0x3c [agpgart] May 1 08:37:16 lithium kernel: [<f91ee330>] ? agp_generic_alloc_user +0x61/0xc3 [agpgart] May 1 08:37:16 lithium kernel: [<f91ee45a>] ? agp_allocate_memory +0x35/0xb3 [agpgart] May 1 08:37:16 lithium kernel: [<f89e00a6>] ? 0xf89e00a6 May 1 08:37:16 lithium kernel: [<f89e0b9b>] ? ttm_tt_populate +0x4d/0x382 [ttm] May 1 08:37:16 lithium kernel: [<f89e0bc6>] ? ttm_tt_populate +0x78/0x382 [ttm] May 1 08:37:16 lithium kernel: [<f89e1c67>] ? ttm_bo_unmap_virtual +0x124/0x455 [ttm] May 1 08:37:16 lithium kernel: [<f89e2db1>] ? ttm_bo_mem_space +0x7a3/0x88b [ttm] May 1 08:37:16 lithium kernel: [<c1022a7f>] ? select_task_rq_fair +0x4c8/0x81d May 1 08:37:16 lithium kernel: [<f89e29a8>] ? ttm_bo_mem_space +0x39a/0x88b [ttm] May 1 08:37:16 lithium kernel: [<f89e31f2>] ? ttm_bo_move_buffer +0x84/0xda [ttm] May 1 08:37:16 lithium kernel: [<f89e32c7>] ? ttm_bo_validate+0x7f/0xc1 [ttm] May 1 08:37:16 lithium kernel: [<f8bc78b0>] ? nouveau_gem_ioctl_cpu_prep+0x23f/0x42c [nouveau] May 1 08:37:16 lithium kernel: [<f8bc8654>] ? nouveau_gem_ioctl_pushbuf +0xbb7/0xbd2 [nouveau] May 1 08:37:16 lithium kernel: [<f93ad46e>] ? drm_ioctl+0x200/0x282 [drm] May 1 08:37:16 lithium kernel: [<f8bc7a9d>] ? nouveau_gem_ioctl_pushbuf +0x0/0xbd2 [nouveau] May 1 08:37:16 lithium kernel: [<f93ad26e>] ? drm_ioctl+0x0/0x282 [drm] May 1 08:37:16 lithium kernel: [<c1078967>] ? vfs_ioctl+0x1c/0x5f May 1 08:37:16 lithium kernel: [<c1078ea2>] ? do_vfs_ioctl+0x451/0x488 May 1 08:37:16 lithium kernel: [<c12e1db8>] ? _spin_unlock_irq+0xd/0x20 May 1 08:37:16 lithium kernel: [<c1029fc1>] ? do_setitimer+0x15c/0x18a May 1 08:37:16 lithium kernel: [<c102a034>] ? sys_setitimer+0x45/0x6f May 1 08:37:16 lithium kernel: [<c1078f05>] ? sys_ioctl+0x2c/0x42 May 1 08:37:16 lithium kernel: [<c10028f4>] ? sysenter_do_call +0x12/0x26 There are about 8 different instances of this, there's a copy of the part I cut out of the logs attached with this e-mail.

In the logs was this: ay 1 10:30:44 lithium kernel: NVRM: Xid (0001:00): 1, Channel 00000000 Method 00000000 Data 01014700 May 1 10:30:44 lithium kernel: NVRM: Xid (0001:00): 36, L1 -> L0 Hmm. Then I had an idea, I tried to run a X11 program (evolution) through a ssh session from another of my machines. At this point I realised what the problem was. One of the X11 libraries had got overwritten somehow. After sshing into the machine from another machine, I ran evolution and it said that libXi was corrupted. The last time this happened, libdl-2.10.1.so got corrupted, which needed a recovery by booting a rescue CD and copying back a new libdl. I'm thinking the interaction between the GART, buffers and the memory on the card itself may, sometimes, overwrite something on rare occasions. This only happens with the Nouveau driver, I have never seen this happen before I switched over. Any ideas this is happening? I'm running the following: nouveau-drm 20100316 xf86-video-nouveau 0.0.15_pre20100329 mesa.git (mesa branch instead of master) linux kernel 2.6.32.8 Thanks -- http://www.munted.org.uk One very high maintenance cat living here.
