it's a Carrizo, A10-8700B R6 Requested logs attached, both running kernel 4.10.0 at moment. Do you need them from 4.11-rc1?
Ok, it's not 4.11 specific.

Some more observation: It seems the hangs happen much more often/frequent with kernel 4.11 than with 4.10. Where 4.10 kernels running usually several days, I have a hang with 4.11 within a day. Additionally I've found some of the WARNING: CPU: 1 PID: 872 at ./include/linux/dma-fence.h:349 amdgpu_vm_grab_id entries in the logs without a hang at this time. As far as I've seen this was always with a 4.10 kernel.
I wonder if there might be memory corruption going on, in which case enabling CONFIG_KASAN for the kernel build might give more clues.
(In reply to Michel Dänzer from comment #7) > I wonder if there might be memory corruption going on, in which case > enabling CONFIG_KASAN for the kernel build might give more clues. I was testing the last days with KASAN enabled and didn't hit one hang or other BUG message in the logs. Today I've upgraded the RAM from one 4G module to two 8G modules and now the first hit directly after boot: [ 104.834811] wlp2s0: authenticate with 02:a0:f9:37:8e:a6 [ 104.838674] ================================================================== [ 104.838715] BUG: KASAN: global-out-of-bounds in iwl_mvm_mac_ctxt_cmd_common+0x14b5/0x1610 [iwlmvm] at addr ffffffffa0d4a336 [ 104.838724] Read of size 2 by task wpa_supplicant/4039 [ 104.838739] Address belongs to variable iwl_drv_exit+0xf66f/0x339 [iwlwifi] [ 104.838750] CPU: 2 PID: 4039 Comm: wpa_supplicant Not tainted 4.11.0-rc7-kasan-00001-g73080f5e1d5b #171 [ 104.838755] Hardware name: HP HP ProBook 645 G2/80FE, BIOS N77 Ver. 01.07 11/01/2016 [ 104.838760] Call Trace: [ 104.838772] dump_stack+0x4f/0x66 [ 104.838781] kasan_report+0x4da/0x510 [ 104.838798] ? iwl_mvm_mac_ctxt_cmd_common+0x14b5/0x1610 [iwlmvm] [ 104.838805] ? update_curr+0x14b/0x490 [ 104.838812] ? wake_atomic_t_function+0x2b0/0x2b0 [ 104.838819] __asan_report_load2_noabort+0x14/0x20 [ 104.838835] iwl_mvm_mac_ctxt_cmd_common+0x14b5/0x1610 [iwlmvm] [ 104.838854] ? iwl_mvm_channel_switch_noa_notif+0x40f/0x410 [iwlmvm] [ 104.838870] ? iwl_mvm_mac_ctxt_send_beacon+0xcb0/0xcb0 [iwlmvm] [ 104.838885] ? iwl_mvm_send_cmd_pdu+0x91/0xb0 [iwlmvm] [ 104.838901] ? iwl_mvm_send_cmd+0x160/0x160 [iwlmvm] [ 104.838917] iwl_mvm_mac_ctxt_cmd_sta+0xd1/0xe70 [iwlmvm] [ 104.838933] ? iwl_mvm_mac_ctxt_cmd_common+0x1610/0x1610 [iwlmvm] [ 104.838949] ? iwl_mvm_phy_ctxt_apply.constprop.3+0x31f/0x5d0 [iwlmvm] [ 104.838966] ? iwl_mvm_ref_taken+0x150/0x150 [iwlmvm] [ 104.838982] iwl_mvm_mac_ctx_send+0x68/0x110 [iwlmvm] [ 104.838996] iwl_mvm_mac_ctxt_changed+0x68/0x180 [iwlmvm] [ 104.839011] iwl_mvm_bss_info_changed+0x2f8/0xec0 [iwlmvm] [ 104.839043] ieee80211_bss_info_change_notify+0x177/0x4c0 [mac80211] [ 104.839070] ? __ieee80211_recalc_txpower+0x111/0x320 [mac80211] [ 104.839097] ieee80211_assign_vif_chanctx+0x7ce/0xf80 [mac80211] [ 104.839123] ieee80211_vif_use_channel+0x3ad/0x780 [mac80211] [ 104.839149] ieee80211_prep_connection+0x55b/0x1cf0 [mac80211] [ 104.839174] ? ieee80211_handle_bss_capability+0x220/0x220 [mac80211] [ 104.839182] ? __kmalloc+0x126/0x220 [ 104.839207] ieee80211_mgd_auth+0x69d/0xdd0 [mac80211] [ 104.839232] ? ieee80211_mlme_notify_scan_completed+0x1c0/0x1c0 [mac80211] [ 104.839261] ieee80211_auth+0x13/0x20 [mac80211] [ 104.839291] cfg80211_mlme_auth+0x2a7/0x6b0 [cfg80211] [ 104.839298] ? unwind_get_return_address+0x1e0/0x1e0 [ 104.839319] ? cfg80211_rx_mgmt+0x710/0x710 [cfg80211] [ 104.839342] ? parse_station_flags.isra.36+0x490/0x490 [cfg80211] [ 104.839363] nl80211_authenticate+0x8f7/0xfe0 [cfg80211] [ 104.839385] ? nl80211_parse_key+0xe70/0xe70 [cfg80211] [ 104.839406] ? nl80211_pre_doit+0xcd/0x560 [cfg80211] [ 104.839414] ? nla_parse+0xde/0x210 [ 104.839422] genl_family_rcv_msg+0x5c8/0x10f0 [ 104.839429] ? __alloc_skb+0x31f/0x560 [ 104.839435] ? genl_rcv+0x40/0x40 [ 104.839443] ? try_to_wake_up+0xb8/0x1080 [ 104.839450] ? alloc_skb_with_frags+0x8d/0x4c0 [ 104.839458] genl_rcv_msg+0x9b/0x120 [ 104.839465] netlink_rcv_skb+0x23b/0x340 [ 104.839471] ? genl_family_rcv_msg+0x10f0/0x10f0 [ 104.839477] genl_rcv+0x23/0x40 [ 104.839483] netlink_unicast+0x438/0x620 [ 104.839489] ? netlink_attachskb+0x640/0x640 [ 104.839497] netlink_sendmsg+0x86f/0xb60 [ 104.839503] ? netlink_broadcast+0x10/0x10 [ 104.839510] ? netlink_broadcast+0x10/0x10 [ 104.839516] sock_sendmsg+0xb5/0xf0 [ 104.839522] ___sys_sendmsg+0x6a2/0x8c0 [ 104.839529] ? ___sys_recvmsg+0x333/0x590 [ 104.839535] ?

(In reply to Michel Dänzer from comment #7) > I wonder if there might be memory corruption going on, in which case > enabling CONFIG_KASAN for the kernel build might give more clues. You're right, KASAN pointet me at two other bugs: https://bugzilla.kernel.org/show_bug.cgi?id=195677 https://bugzilla.kernel.org/show_bug.cgi?id=196145 After eliminating this, no more problems with amdgpu happened. Closing this report as invalid.
