Hi. I have experimented random crashes (system hangs - reboot necessary) on my asus U30J i915 / nouveau. At the moment, I am still unable to switch to nvidia graphics. So I am using intel i915 with xorg intel drivers. x11-drivers/xf86-video-intel 2.13.0 x11-base/xorg-server 1.9.2.902 kernel 2.6.36 I can reproduce it quite easily by - booting the machine - building something with make -j5 after some seconds or minutes I find the machine is hung. Sometimes the screen is black (maybe because meanwhile power management has turned the screen off), sometimes the screen is simply freezed. Must force shutdown. No traces in the logs. I attach my kernel configuration Below the output of lsmod: Module Size Used by aes_generic 25810 2 ipv6 214881 24 sco 7460 2 bnep 8846 2 rfcomm 28783 4 l2cap 32539 16 bnep,rfcomm snd_hda_codec_intelhdmi 8975 1 snd_hda_codec_realtek 252628 1 btusb 9505 2 bluetooth 43397 9 sco,bnep,rfcomm,l2cap,btusb uvcvideo 50136 0 videodev 36742 1 uvcvideo v4l1_compat 11138 2 uvcvideo,videodev v4l2_compat_ioctl32 8241 1 videodev arc4 1242 2 ecb 1809 2 sg 23620 0 ath9k 64416 0 snd_hda_intel 18979 1 nouveau 473119 0 i915 237778 3 snd_hda_codec 50940 3 snd_hda_codec_intelhdmi,snd_hda_codec_realtek,snd_hda_intel ath9k_common 3982 1 ath9k ttm 43304 1 nouveau snd_hwdep 4982 1 snd_hda_codec ath9k_hw 258491 2 ath9k,ath9k_common snd_pcm 55140 2 snd_hda_intel,snd_hda_codec video 18530 1 i915 thermal 11978 0 drm_kms_helper 20239 2 nouveau,i915 drm 142558 5 nouveau,i915,ttm,drm_kms_helper processor 23453 0 snd_timer 15737 1 snd_pcm thermal_sys 11974 3 video,thermal,processor rtc_cmos 7998 0 ath 8226 2 ath9k,ath9k_hw rtc_core 11253 1 rtc_cmos i2c_algo_bit 4439 2 nouveau,i915 cfbcopyarea 2910 2 nouveau,i915 atl1c 26623 0 mac80211 128483 2 ath9k,ath9k_common i2c_core 16008 6 videodev,nouveau,i915,drm_kms_helper,drm,i2c_algo_bit asus_laptop 12952 0 ehci_hcd 30917 0 snd 45335 8 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer usbcore 123954 4 btusb,uvcvideo,ehci_hcd intel_agp 25646 2 i915 cfg80211 123464 4 ath9k,ath9k_common,ath,mac80211 button 4634 2 nouveau,i915 battery 5433 0 soundcore 4809 1 snd agpgart 24358 3 ttm,drm,intel_agp hwmon 1329 1 thermal_sys sparse_keymap 2043 1 asus_laptop rtc_lib 1609 1 rtc_core snd_page_alloc 5833 2 snd_hda_intel,snd_pcm ac 2112 0 cfbimgblt 1881 2 nouveau,i915 rfkill 13380 4 bluetooth,asus_laptop,cfg80211 output 1612 1 video cfbfillrect 2954 2 nouveau,i915 Thanks
Does it make any difference if the nouveau module is never loaded? Does it make any difference if i915 is never loaded?
Duping to the linked regression tracker. *** This bug has been marked as a duplicate of bug 24752 ***
The nouveau module wasn't even compiled when the crash used to happen. Another detail: kms was built as a module and the machine booted with kernel parameter i915 modeset=1. In the kernel 2.6.35 to which I switched back (and where I still haven't run into this issue so far) kms for intel is built in. I did not try to switch to nvidia drivers yet. To do that I would have to blacklist i915 and install nvidia proprietary drivers I think... so far vga switcheroo does not work for me and nvidia proprietary drivers hang the machine if i915 is loaded.
