https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D280546 --- Comment #17 from Robin Haberkorn <robin.haberkorn@googlemail.com> --- Well except, that it doesn't. Because it's obviously a memory corruption is= sue: (kgdb) f 8 #8 iwl_mvm_bt_notif_per_link (mvm=3D0xfffffe00f1bb2508, vif=3D0xfffffe00f3= 3cde80, data=3D0xfffffe00c294bd40, link_id=3D0) at /usr/src/sys/contrib/dev/iwlwifi/mvm/coex.c:292 292 chanctx_conf->def.chan->band !=3D NL80211_BAND_2GHZ)) { (kgdb) f 8 #8 iwl_mvm_bt_notif_per_link (mvm=3D0xfffffe00f1bb2508, vif=3D0xfffffe00f3= 3cde80, data=3D0xfffffe00c294bd40, link_id=3D0) at /usr/src/sys/contrib/dev/iwlwifi/mvm/coex.c:292 292 chanctx_conf->def.chan->band !=3D NL80211_BAND_2GHZ)) { (kgdb) p chanctx_conf->def.chan $1 =3D (struct linuxkpi_ieee80211_channel *) 0x8086b85b (kgdb) p *chanctx_conf->def.chan Cannot access memory at address 0x8086b85b It's only sometimes resulting in unexpected NULL pointers. bz@FreeBSD.org, perhaps it would be worth to pull in upstream patches? The = last update was in May of 2023. Actually, considering that this driver is suppos= ed to be synced with the Linux kernel version, shouldn't that be the first thi= ng we try? --=20 You are receiving this mail because: You are on the CC list for the bug.=
