** Description changed: I have fglrx drivers in my hybrid fglrx/intel system and I am using the integrated GPU, setup by: amdconfig --px-igpu The problem is that every second boot the X server crashes, which means: - One time the X server loads normally ** - One time the X server crashes, giving the error in the attached log and the only thing I can do is reboot the system This periodic behaviour is totally reproducible: once it crashes, after the reboot it works fine, on the next reboot crashes again, and so on... ** I had to use the patched fglrx/intel drivers from: https://launchpad.net/~andrikos/+archive/ppa in order to avoid Bug #1068404 + + + WORKAROUND: An obvious workaround (not a solution) is to use the discrete ATI GPU by giving: + amdconfig --px-dgpu + [ 34.540409] BUG: unable to handle kernel paging request at ffffc90015b48700 [ 34.540447] IP: [<ffffffffa01964d7>] _ZN8AsicR6007getRptrE12_QS_CP_RING_+0x7/0x10 [fglrx] [ 34.540547] PGD 12b020067 PUD 12b021067 PMD 10ceed067 PTE 0 [ 34.540574] Oops: 0000 [#1] SMP [ 34.540591] CPU 0 [ 34.540599] Modules linked in: pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) parport_pc rfcomm ppdev bnep binfmt_misc snd_hda_codec_hdmi snd_hda_codec_realtek coretemp kvm_intel kvm ghash_clmulni _intel cryptd btusb bluetooth uvcvideo videobuf2_core videodev videobuf2_vmalloc videobuf2_memops joydev microcode snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_seq_midi arc4 snd_rawmidi snd_seq_midi_event s nd_seq snd_timer snd_seq_device psmouse serio_raw mac_hid sony_laptop snd ath9k mei i915 drm_kms_helper fglrx(PO) drm soundcore snd_page_alloc i2c_algo_bit video mac80211 ath9k_common lpc_ich ath9k_hw ath cfg80211 amd_iommu_v2 lp parport hid_generic usbhid hid mmc_bloc k atl1c sdhci_pci sdhci [ 34.540911] [ 34.540915] Pid: 1204, comm: Xorg Tainted: P O 3.5.0-20-generic #31-Ubuntu Sony Corporation VPCCB2S1E/VAIO [ 34.540956] RIP: 0010:[<ffffffffa01964d7>] [<ffffffffa01964d7>] _ZN8AsicR6007getRptrE12_QS_CP_RING_+0x7/0x10 [fglrx] [ 34.541045] RSP: 0018:ffff8801079c9cf0 EFLAGS: 00010246 [ 34.541065] RAX: 0000000000000001 RBX: ffffffffa02a8830 RCX: 0000000000000007 [ 34.541090] RDX: ffffc90015b40000 RSI: 0000000000000000 RDI: ffffc9001674b020 [ 34.541115] RBP: ffffc90016b6f140 R08: 0000000000000004 R09: ffffc9001674b020 [ 34.541141] R10: 0000000000000000 R11: ffff88010c880500 R12: ffffc9001674b198 [ 34.541166] R13: ffff88010db80000 R14: ffff88010db80000 R15: 0000000000000000 [ 34.541193] FS: 00007f19d9cbd880(0000) GS:ffff88012fa00000(0000) knlGS:0000000000000000 [ 34.541222] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 34.541243] CR2: ffffc90015b48700 CR3: 00000001079c4000 CR4: 00000000000407f0 [ 34.541268] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 34.541295] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 34.541320] Process Xorg (pid: 1204, threadinfo ffff8801079c8000, task ffff880108039700) [ 34.541349] Stack: [ 34.541357] ffffffffa0179535 ffff8801079c9d48 ffffc9001674b020 0000000000000000 [ 34.542796] ffffffffa0197ba9 ffff88010db80000 0000000000000000 ffff880107a6d120 [ 34.544219] ffffffffa014aff4 ffff880107a6d120 ffffffffa0103dfa ffff8801079c9d58 [ 34.545661] Call Trace: [ 34.547115] [<ffffffffa0179535>] ? _ZN15ExecutableUnits17assertPrimaryRingEb+0x1e5/0x220 [fglrx] [ 34.548603] [<ffffffffa0197ba9>] ? _ZN8AsicR6009assertPM4Eb+0x39/0x80 [fglrx] [ 34.550077] [<ffffffffa014aff4>] ?
