Hey everyone. I've been using linux-rt-3.0 series, which has been very stable using the nvidia proprietary drivers (pretty much flawlessly, actually). I had used rt-3.0 with nvidia all the way upto nvidia version 290.35. I never experienced any problems relating to nvidia, at all... But external/other reasons, recently I have upgraded to rt-3.2 which also seems to be working quite well. At the same time, i also upgraded my nvidia driver to the latest available driver, which is 302.07 (beta). I know many of the RT devs aren't huge fans of the nvidia blob, but i would like to know whether this is an nvidia bug or rt bug; [143335.564097] BUG: scheduling while atomic: irq/19-nvidia/1141/0x00000002 [143335.564099] Modules linked in: snd_usb_audio ipv6 snd_seq_midi snd_seq_midi_event snd_seq_dummy snd_hrtimer snd_seq joydev wacom(O) vmnet(O) fuse vsock(O) vmci(O) vmmon(O) bnep bluetooth rfkill hwmon_vid snd_usb_us122l snd_usbmidi_lib snd_rawmidi snd_seq_device snd_hda_codec_via snd_hda_codec snd_hwdep snd_pcm forcedeth evdev snd_page_alloc edac_mce_amd firewire_ohci edac_core firewire_core wmi k10temp crc_itu_t video asus_atk0110 psmouse serio_raw snd_timer snd soundcore button i2c_nforce2 processor nvidia(P) i2c_core ext4 crc16 jbd2 mbcache usbhid hid sd_mod pata_amd pata_acpi ahci uhci_hcd libahci ata_generic ohci_hcd libata ehci_hcd scsi_mod usbcore usb_common [last unloaded: snd_hda_codec_hdmi] [143335.564127] Pid: 1141, comm: irq/19-nvidia Tainted: P O 3.2.16-rt27-1-rt #1 [143335.564128] Call Trace: [143335.564134] [<ffffffff81415afa>] __schedule_bug+0x5f/0x63 [143335.564137] [<ffffffff8141bb92>] __schedule+0x842/0x8b0 [143335.564140] [<ffffffff8141dde0>] ? _raw_spin_unlock_irqrestore+0x10/0x40 [143335.564141] [<ffffffff8141de07>] ? _raw_spin_unlock_irqrestore+0x37/0x40 [143335.564144] [<ffffffff8109a755>] ? task_blocks_on_rt_mutex+0x1a5/0x210 [143335.564146] [<ffffffff8141c0ae>] schedule+0x2e/0xa0 [143335.564147] [<ffffffff8141d71c>] rt_spin_lock_slowlock+0x114/0x1f8 [143335.564149] [<ffffffff8141d996>] rt_spin_lock+0x26/0x30 [143335.564151] [<ffffffff8105a4a6>] __wake_up+0x36/0x70 [143335.564259] [<ffffffffa0837783>] nv_post_event+0xe3/0x120 [nvidia] [143335.564297] [<ffffffffa080c8ce>] _nv014670rm+0xe8/0x141 [nvidia] [143335.564367] [<ffffffffa04d3928>] ? _nv006157rm+0xc0/0xe9 [nvidia] [143335.564436] [<ffffffffa04d3be2>] ? _nv013751rm+0xdf/0xf8 [nvidia] [143335.564504] [<ffffffffa04d3b62>] ? _nv013751rm+0x5f/0xf8 [nvidia] [143335.564581] [<ffffffffa0642bdf>] ? _nv010689rm+0xece/0x10ec [nvidia] [143335.564657] [<ffffffffa0642bf8>] ? _nv010689rm+0xee7/0x10ec [nvidia] [143335.564714] [<ffffffffa06b378b>] ? _nv013099rm+0x8b8/0xc74 [nvidia] [143335.564770] [<ffffffffa06bc932>] ? _nv013078rm+0xf2/0x137 [nvidia] [143335.564805] [<ffffffffa08106b3>] ? _nv001098rm+0x143/0x1c2 [nvidia] [143335.564840] [<ffffffffa08172d7>] ? rm_isr_bh+0x23/0x66 [nvidia] [143335.564874] [<ffffffffa0835532>] ? nv_kern_isr_bh+0x42/0x70 [nvidia] [143335.564876] [<ffffffff81068f11>] ? __tasklet_action.isra.9+0x71/0x150 [143335.564878] [<ffffffff8106909e>] ? tasklet_action+0x5e/0x60 [143335.564880] [<ffffffff8106826b>] ? __do_softirq_common+0xcb/0x240 [143335.564882] [<ffffffff81069360>] ? __do_softirq+0x10/0x20 [143335.564883] [<ffffffff810694ad>] ? local_bh_enable+0x13d/0x160 [143335.564885] [<ffffffff810c657b>] ? irq_forced_thread_fn+0x4b/0x70 [143335.564887] [<ffffffff810c6438>] ? irq_thread+0x158/0x200 [143335.564888] [<ffffffff810c6530>] ? irq_thread_fn+0x50/0x50 [143335.564889] [<ffffffff810c62e0>] ? irq_finalize_oneshot+0x110/0x110 [143335.564891] [<ffffffff8108414c>] ? kthread+0x8c/0xa0 [143335.564893] [<ffffffff81050449>] ? finish_task_switch+0x49/0xf0 [143335.564896] [<ffffffff81420b34>] ? kernel_thread_helper+0x4/0x10 [143335.564898] [<ffffffff810840c0>] ? __init_kthread_worker+0x60/0x60 [143335.564899] [<ffffffff81420b30>] ? gs_change+0x13/0x13 [ninez@ninez ~]$ if this is an nvidia problem (which i assume it is), i would like to report it to them (and obviously, if it is an rt related bug - i would like to report it here. I am using an rt-patch for the nvidia driver. I simply adapted an existing package for my distro (Archlinux). the patch is available here, in case it matters; https://aur.archlinux.org/packages.php?ID=12132 the patch can be viewed by downloading the 'tarball'. I only mention the patch in case it matters. any other info you may need, just ask and i will do my best to provide it. thank you. jordan -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
