Yes, the recent fix by David should paper over it: http://lore.kernel.org/r/alpine.DEB.2.22.394.2006110025250.13899@chino.kir.corp.google.com IIRC, Christoph already merged it in his tree. I also made another fix series in the sound driver side (found in topic/dma-fix2 branch in my sound.git tree). But I guess I'll queue it for 5.9 after more testing. thanks, Takashi > [ 9.791309] BUG: unable to handle page fault for address: > ffffb1e78165d000 > [ 9.791328] #PF: supervisor write access in kernel mode > [ 9.791330] #PF: error_code(0x000b) - reserved bit violation > [ 9.791332] PGD 23dd5c067 P4D 23dd5c067 PUD 23dd5d067 PMD 22ba8e067 > PTE 80001a3681509163 > [ 9.791337] Oops: 000b [#1] SMP NOPTI > [ 9.791340] CPU: 7 PID: 866 Comm: pulseaudio Not tainted 5.8.0-rc1 #1 > [ 9.791341] Hardware name: LENOVO 10VGCTO1WW/3130, BIOS M1XKT45A > 08/21/2019 > [ 9.791346] RIP: 0010:__memset+0x24/0x30 > [ 9.791348] Code: cc cc cc cc cc cc 0f 1f 44 00 00 49 89 f9 48 89 > d1 83 e2 07 48 c1 e9 03 40 0f b6 f6 48 b8 01 01 01 01 01 01 01 01 48 > 0f af c6 48 ab 89 d1 f3 aa 4c 89 c8 c3 90 49 89 f9 40 88 f0 48 89 > d1 f3 > [ 9.791350] RSP: 0018:ffffb1e7817a7dd0 EFLAGS: 00010216 > [ 9.791352] RAX: 0000000000000000 RBX: ffff97b32dfd7400 RCX: > 00000000000008a0 > [ 9.791354] RDX: 0000000000000000 RSI: 0000000000000000 RDI: > ffffb1e78165d000 > [ 9.791356] RBP: ffffb1e7817a7e00 R08: ffffb1e780000000 R09: > ffffb1e78165d000 > [ 9.791358] R10: ffffffffffffffff R11: ffffb1e78165d000 R12: > 0000000000000000 > [ 9.791359] R13: ffff97b32dfd3000 R14: ffffffffc0b48880 R15: > ffff97b33aa42600 > [ 9.791361] FS: 00007fa11cb34ec0(0000) GS:ffff97b33edc0000(0000) > knlGS:0000000000000000 > [ 9.791363] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 > [ 9.791365] CR2: ffffb1e78165d000 CR3: 0000000210db6000 CR4: > 00000000003406e0 > [ 9.791367] Call Trace: > [ 9.791377] ? snd_pcm_hw_params+0x3ca/0x440 [snd_pcm] > [ 9.791383] snd_pcm_common_ioctl+0x173/0xf20 [snd_pcm] > [ 9.791389] ? snd_ctl_ioctl+0x1c5/0x710 [snd] > [ 9.791394] snd_pcm_ioctl+0x27/0x40 [snd_pcm] > [ 9.791398] ksys_ioctl+0x9d/0xd0 > [ 9.791400] __x64_sys_ioctl+0x1a/0x20 > [ 9.791404] do_syscall_64+0x49/0xc0 > [ 9.791406] entry_SYSCALL_64_after_hwframe+0x44/0xa9 > [ 9.791408] RIP: 0033:0x7fa11d4c137b > [ 9.791410] Code: Bad RIP value. > [ 9.791412] RSP: 002b:00007ffe2fb4e308 EFLAGS: 00000246 ORIG_RAX: > 0000000000000010 > [ 9.791414] RAX: ffffffffffffffda RBX: 00007ffe2fb4e510 RCX: > 00007fa11d4c137b > [ 9.791415] RDX: 00007ffe2fb4e510 RSI: 00000000c2604111 RDI: > 0000000000000012 > [ 9.791417] RBP: 000055e99f65a890 R08: 0000000000000000 R09: > 0000000000000000 > [ 9.791418] R10: 0000000000000004 R11: 0000000000000246 R12: > 000055e99f65a810 > [ 9.791420] R13: 00007ffe2fb4e344 R14: 0000000000000000 R15: > 00007ffe2fb4e510 > [ 9.791422] Modules linked in: cmac algif_hash algif_skcipher > af_alg bnep binfmt_misc nls_iso8859_1 snd_hda_codec_realtek > snd_hda_codec_generic ledtrig_audio snd_hda_codec_hdmi snd_hda_intel > snd_usb_audio snd_intel_dspcfg snd_usbmidi_lib snd_hda_codec amdgpu mc > snd_hda_core snd_hwdep snd_pcm edac_mce_amd iommu_v2 ath10k_pci > snd_seq_midi gpu_sched snd_seq_midi_event kvm_amd kvm ttm snd_rawmidi > ath10k_core irqbypass drm_kms_helper snd_seq cec i2c_algo_bit > fb_sys_fops ath snd_seq_device syscopyarea snd_timer mac80211 > crct10dif_pclmul ghash_clmulni_intel btusb aesni_intel btrtl btbcm > crypto_simd cryptd btintel serio_raw input_leds sysfillrect > glue_helper bluetooth efi_pstore k10temp snd pl2303 wmi_bmof > ecdh_generic ecc snd_pci_acp3x sysimgblt cfg80211 soundcore ccp > libarc4 ipmi_devintf ipmi_msghandler mac_hid sch_fq_codel parport_pc > ppdev lp parport drm ip_tables x_tables autofs4 hid_generic usbhid hid > crc32_pclmul nvme ahci psmouse i2c_piix4 libahci nvme_core r8169 > realtek wmi video > [ 9.791463] CR2: ffffb1e78165d000 > [ 9.791465] ---[ end trace 7b22a028ccaf2e75 ]--- > > thanks, > -- Shuah >
