If I enable the HDMI audio using the Mobility Radeon HD 5650 card with kernel 3.10.0 (or newer), I get a kernel oops that prevents me to boot. This is a regression, since everything is fine with kernel 3.9.0. Also, when I enable the switchable graphics in the bios, the notebook boots but as soon as I use vgaswitcheroo to switch to the discrete card, I still get a black screen and the system can't be used (when restoring the integrate card, it goes back to work). This is the kernel failure I've found: Jul 8 23:23:03 tricky kernel: [ 30.386559] BUG: unable to handle kernel NULL pointer dereference at (null) Jul 8 23:23:03 tricky kernel: [ 30.386626] IP: [<ffffffffa024be90>] evergreen_hdmi_enable+0x20/0x90 [radeon] Jul 8 23:23:03 tricky kernel: [ 30.386715] PGD 0 Jul 8 23:23:03 tricky kernel: [ 30.386731] Oops: 0000 [#1] SMP Jul 8 23:23:03 tricky kernel: [ 30.387209] CPU: 2 PID: 2184 Comm: Xorg Not tainted 3.10.0-996-generic #201307020454 Jul 8 23:23:03 tricky kernel: [ 30.387260] Hardware name: Acer Aspire 4820TG/JM41_CP, BIOS V1.25 03/16/2011 Jul 8 23:23:03 tricky kernel: [ 30.387306] task: ffff88022c33ddc0 ti: ffff88022f3d2000 task.ti: ffff88022f3d2000 Jul 8 23:23:03 tricky kernel: [ 30.387354] RIP: 0010:[<ffffffffa024be90>] [<ffffffffa024be90>] evergreen_hdmi_enable+0x20/0x90 [radeon] Jul 8 23:23:03 tricky kernel: [ 30.387447] RSP: 0018:ffff88022f3d3b68 EFLAGS: 00010246 Jul 8 23:23:03 tricky kernel: [ 30.387482] RAX: ffff88022b02de00 RBX: ffff88022b02ea00 RCX: 0000000000000007 Jul 8 23:23:03 tricky kernel: [ 30.387529] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff88022b02ea00 Jul 8 23:23:03 tricky kernel: [ 30.387575] RBP: ffff88022f3d3b78 R08: 0000000000000023 R09: 0000000000000022 Jul 8 23:23:03 tricky kernel: [ 30.387621] R10: ffff88022b724880 R11: 0000000000000000 R12: ffff88022b1f0000 Jul 8 23:23:03 tricky kernel: [ 30.387667] R13: ffff88022bb13000 R14: ffff88022bb13000 R15: ffff8802307e6000 Jul 8 23:23:03 tricky kernel: [ 30.387716] FS: 00007f34c3505980(0000) GS:ffff88023bc80000(0000) knlGS:0000000000000000 Jul 8 23:23:03 tricky kernel: [ 30.387768] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Jul 8 23:23:03 tricky kernel: [ 30.387807] CR2: 0000000000000000 CR3: 000000022ed44000 CR4: 00000000000007e0 Jul 8 23:23:03 tricky kernel: [ 30.387854] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Jul 8 23:23:03 tricky kernel: [ 30.387901] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Jul 8 23:23:03 tricky kernel: [ 30.387947] Stack: Jul 8 23:23:03 tricky kernel: [ 30.387963] ffff88022b1f0000 ffff88022bb13000 ffff88022f3d3ba8 ffffffffa0252f3f Jul 8 23:23:03 tricky kernel: [ 30.388016] ffff88022b02ea00 ffff88022bb13478 ffff88022bb13000 00000000ffffffde Jul 8 23:23:03 tricky kernel: [ 30.388070] ffff88022f3d3bd8 ffffffffa010ab3a ffff88022e4b7cf0 ffff8802307e6000 Jul 8 23:23:03 tricky kernel: [ 30.388122] Call Trace: Jul 8 23:23:03 tricky kernel: [ 30.388173] [<ffffffffa0252f3f>] radeon_atom_encoder_disable+0x15f/0x170 [radeon] Jul 8 23:23:03 tricky kernel: [ 30.388231] [<ffffffffa010ab3a>] drm_helper_disable_unused_functions+0x14a/0x190 [drm_kms_helper] Jul 8 23:23:03 tricky kernel: [ 30.388295] [<ffffffffa010c5fe>] drm_crtc_helper_set_config+0x95e/0xb50 [drm_kms_helper] Jul 8 23:23:03 tricky kernel: [ 30.388357] [<ffffffffa00931f8>] ? ttm_bo_vm_fault+0x288/0x3f0 [ttm] Jul 8 23:23:03 tricky kernel: [ 30.388420] [<ffffffffa01effec>] ? radeon_ttm_fault+0x5c/0x70 [radeon] Jul 8 23:23:03 tricky kernel: [ 30.388482] [<ffffffffa0040fec>] drm_mode_set_config_internal+0x5c/0xe0 [drm] Jul 8 23:23:03 tricky kernel: [ 30.388540] [<ffffffffa0043cd8>] drm_mode_setcrtc+0x2e8/0x540 [drm] Jul 8 23:23:03 tricky kernel: [ 30.388589] [<ffffffff811617e6>] ? handle_pte_fault+0x96/0x230 Jul 8 23:23:03 tricky kernel: [ 30.388639] [<ffffffffa003352a>] drm_ioctl+0x50a/0x650 [drm] Jul 8 23:23:03 tricky kernel: [ 30.388689] [<ffffffffa00439f0>] ? drm_mode_setplane+0x3f0/0x3f0 [drm] Jul 8 23:23:03 tricky kernel: [ 30.390589] [<ffffffff8109339c>] ? account_user_time+0x9c/0xb0 Jul 8 23:23:03 tricky kernel: [ 30.392510] [<ffffffff811b2368>] do_vfs_ioctl+0x88/0x340 Jul 8 23:23:03 tricky kernel: [ 30.394435] [<ffffffff811b26b1>] SyS_ioctl+0x91/0xb0 Jul 8 23:23:03 tricky kernel: [ 30.396255] [<ffffffff8171822f>] tracesys+0xe1/0xe6 Jul 8 23:23:03 tricky kernel: [ 30.397670] Code: d6 de ff eb 9b e8 91 d0 e0 e0 90 66 66 66 66 90 55 48 89 e5 48 83 ec 10 48 8b 87 50 01 00 00 40 84 f6 48 8b 90 08 01 00 00 75 20 <80> 3a 00 74 5c c6 02 00 48 8b 80 08 01 00 00 49 c7 c0 69 b4 2c Jul 8 23:23:03 tricky kernel: [ 30.400952] RIP [<ffffffffa024be90>] evergreen_hdmi_enable+0x20/0x90 [radeon] Jul 8 23:23:03 tricky kernel: [ 30.402658] RSP <ffff88022f3d3b68> Jul 8 23:23:03 tricky kernel: [ 30.404355] CR2: 0000000000000000 Jul 8 23:23:03 tricky kernel: [ 30.411223] ---[ end trace cf93979ade0a2572 ]---
