--- Comment #2 from Michal Krenek (Mikos) <m.kre...@gmail.com> 2010-06-18 22:09:46 --- Created an attachment (id=26852) --> (https://bugzilla.kernel.org/attachment.cgi?id=26852) First patch attempt by glisse (this doesn't work) I have already discussed this issue on #radeon IRC channel with glisse and he gave me this patch, but unfortunately it doesn't work. After applying this patch and recompiling kernel, everything seems good (HDTV is again properly detected by xrandr) until I try to activate HDMI output with xrandr. After it main laptop LVDS screen get garbled and graphics system completely freezes (but I still can SSH into system). This is relevant error from dmesg: ------------[ cut here ]------------ kernel BUG at kernel/timer.c:662! invalid opcode: 0000 [#1] PREEMPT SMP last sysfs file: /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:14/PNP0C09:00/PNP0C0A:00/power_supply/BAT1/charge_full Modules linked in: rfcomm sco bridge stp llc bnep l2cap crc16 snd_hda_codec_atihdmi arc4 fuse ecb tun cpufreq_powersave cpufreq_ondemand snd_seq_dummy powernow_k8 freq_table snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss snd_hda_codec_realtek video mperf output ac battery snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_timer snd ath5k soundcore snd_page_alloc sdhci_pci sdhci mmc_core processor thermal mac80211 button btusb ath radeon bluetooth joydev cfg80211 uvcvideo videodev v4l1_compat rfkill led_class ttm k8temp drm_kms_helper ati_agp i2c_piix4 psmouse evdev r8169 mii pcspkr sg shpchp pci_hotplug serio_raw drm agpgart i2c_algo_bit i2c_core rtc_cmos rtc_core rtc_lib jfs ohci_hcd ehci_hcd usbcore sd_mod sr_mod ahci libahci cdrom ata_generic pata_atiixp pata_acpi libata scsi_mod Pid: 4113, comm: X Not tainted 2.6.35-rc3-rc #1 MS-1222/PR210 EIP: 0060:[<c1051e58>] EFLAGS: 00213246 CPU: 1 EIP is at mod_timer+0x278/0x2a0 EAX: 00000000 EBX: f695b788 ECX: 00000000 EDX: 00000000 ESI: 0001aaa8 EDI: 0001aaa8 EBP: f53f1b68 ESP: f53f1b4c DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Process X (pid: 4113, ti=f53f0000 task=f66fd590 task.ti=f53f0000) Stack: 0000018f f53f1bb0 00000000 00000000 f6012200 f695a000 00007400 f53f1b8c <0> f8e8b77c 00000001 f8eb6a2e f8ea5af0 f8eb6a10 00000000 f695a000 f6012200 <0> f53f1bc4 f8e8ca5f f8e2eb79 f53f1bb0 f695a000 f695a000 f7353700 f53f1bc4 Call Trace: [<f8e8b77c>] ? r600_audio_enable_polling+0x6c/0x80 [radeon] [<f8e8ca5f>] ? r600_hdmi_enable+0x1cf/0x490 [radeon] [<f8e2eb79>] ? atom_execute_table+0x49/0x60 [radeon] [<f8e3c8d7>] ? radeon_atom_encoder_mode_set+0x227/0x2e0 [radeon] [<f8b42d58>] ? drm_crtc_helper_set_mode+0x3c8/0x3f0 [drm_kms_helper] [<f8b435f8>] ? drm_crtc_helper_set_config+0x758/0x7e0 [drm_kms_helper] [<c12e0eda>] ? __mutex_lock_slowpath+0x1ea/0x2b0 [<f89a1010>] ? drm_mode_setcrtc+0x260/0x330 [drm] [<c118a010>] ? __copy_from_user_ll+0x40/0xf0 [<f89a1cae>] ? drm_mode_gamma_set_ioctl+0x3e/0xf0 [drm] [<f89952fe>] ? drm_ioctl+0x1ae/0x410 [drm] [<f89a0db0>] ? drm_mode_setcrtc+0x0/0x330 [drm] [<c115d6df>] ? security_file_permission+0xf/0x20 [<c10f5d1d>] ? rw_verify_area+0x5d/0xd0 [<c1103b74>] ? vfs_ioctl+0x34/0xa0 [<f8995150>] ? drm_ioctl+0x0/0x410 [drm] [<c1104286>] ? do_vfs_ioctl+0x66/0x560 [<c10498b1>] ? __do_softirq+0xe1/0x1e0 [<c10f68cf>] ? vfs_writev+0x4f/0x60 [<c11047df>] ? sys_ioctl+0x5f/0x80 [<c100379f>] ? sysenter_do_call+0x12/0x28 Code: 12 8b 0e 8b 46 04 83 c6 08 89 da ff d1 8b 0e 85 c9 75 f0 89 e0 25 00 e0 ff ff 83 68 14 01 f6 40 08 08 75 18 8b 03 e9 03 fe ff ff <0f> 0b 8b 55 04 89 d8 e8 ac fa ff ff e9 be fd ff ff e8 c2 de 28 EIP: [<c1051e58>] mod_timer+0x278/0x2a0 SS:ESP 0068:f53f1b4c ---[ end trace 376f66ebcc7033eb ]--- -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
