No experimental mesa drivers now, but still I only get 3d accelerations with the experimental mesa drivers. I also get some errors on startup about nouveau driver (on both kernels) and a error about a USB device file with the rt-kernel. I was using supercollider, jack and ardour. The oops bug report is here: Package: kernel Latest Crash: Sat 07 Aug 2010 05:14:44 PM Command: not_applicable Reason: BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 Comment: None Bug Reports: BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 IP: [] ttm_tt_swapout+0x92/0x1c9 [ttm] PGD 11009b067 PUD 10ce2f067 PMD 0 Oops: 0000 [#1] PREEMPT SMP last sysfs file: /sys/devices/system/cpu/cpu7/cache/index2/shared_cpu_map CPU 1 Pid: 326, comm: ttm_swap Not tainted 2.6.33.6-147.2.4.rt28.1.fc13.ccrma.x86_64.rt #1 43192PU/43192PU RIP: 0010:[] [] ttm_tt_swapout+0x92/0x1c9 [ttm] RSP: 0018:ffff88012b3afcb0 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff8800b0f20640 RCX: 0000000000000000 RDX: ffff88012b3b8780 RSI: ffff88010e9375c0 RDI: ffff8800b0f20640 RBP: ffff88012b3afd10 R08: 0000000000000022 R09: 0000000000000002 R10: ffff8800b0f20640 R11: 0000000000000004 R12: ffff88010e9375c0 R13: ffff88010e9375c0 R14: ffff88010ce42090 R15: ffff88012ac623c0 FS: 0000000000000000(0000) GS:ffff880006240000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000048 CR3: 0000000129516000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process ttm_swap (pid: 326, threadinfo ffff88012b3ae000, task ffff88012b3b8780) Stack: 0000000000105ee0 0000000000105eef ffff88012a143108 000000000000bdc7 0000000100000000 ffff88010ce42000 ffff88010ce42044 ffff88010ce42000 ffff88010ce42044 0000000000000000 ffff88010ce42090 ffff88012ac623c0 Call Trace: [] ttm_bo_swapout+0x1ee/0x22e [ttm] [] ttm_shrink+0x9d/0xc4 [ttm] [] ttm_shrink_work+0x14/0x16 [ttm] [] worker_thread+0x1d8/0x275 [] ? ttm_shrink_work+0x0/0x16 [ttm] [] ? autoremove_wake_function+0x0/0x34 [] ? worker_thread+0x0/0x275 [] kthread+0x7a/0x82 [] kernel_thread_helper+0x4/0x10 [] ? kthread+0x0/0x82 [] ? kernel_thread_helper+0x0/0x10 Code: e8 26 00 06 e1 48 3d 00 f0 ff ff 49 89 c4 76 16 48 c7 c7 66 7c 07 a0 31 c0 45 89 e6 e8 6c b7 3c e1 e9 2a 01 00 00 49 8b 44 24 18 <48> 8b 40 48 4c 8b b8 50 01 00 00 c7 45 c4 00 00 00 00 65 48 8b RIP [] ttm_tt_swapout+0x92/0x1c9 [ttm] RSP CR2: 0000000000000048 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
