https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273985 Bug ID: 273985 Summary: iwlwifi crash on ifconfig wlan0 destroy Product: Base System Version: 13.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: wireless Assignee: wireless@FreeBSD.org Reporter: che@bein.link FreeBSD-13.2-RELEASE-p3. amd64. ThinkPad T14s gen 1. As many people have mentioned, iwlwifi isn't that stable. In my case, __sometimes__ (more often after total connectivity loss or UDP failure) iwl= wifi crashes the system on wlan0 destruction. Here's the backtrace: (lldb) bt * thread #1, name =3D '(pid 3984) ifconfig (crashed)' * frame #0: 0xffffffff80c065ae kernel`doadump + 46 frame #1: 0xffffffff80c0638a kernel`kern_reboot + 1082 frame #2: 0xffffffff80c0682e kernel`vpanic + 446 frame #3: 0xffffffff80c06663 kernel`panic + 67 frame #4: 0xffffffff810b1fa7 kernel`trap_fatal + 903 frame #5: 0xffffffff810b1fff kernel`trap_pfault + 79 frame #6: 0xffffffff81088ed8 kernel`calltrap + 8 frame #7: 0xfffffe012388e1b0 frame #8: 0xffffffff80d8f873 kernel`ieee80211_node_psq_drain + 243 frame #9: 0xffffffff80d83907 kernel`node_cleanup + 167 frame #10: 0xffffffff80d83825 kernel`node_free + 37 frame #11: 0xffffffff80d83f3b kernel`ieee80211_node_vdetach + 43 frame #12: 0xffffffff80d5bd7b kernel`ieee80211_vap_detach + 1099 frame #13: 0xffffffff80e47d7b kernel`lkpi_ic_vap_delete + 171 frame #14: 0xffffffff80d22931 kernel`ifc_simple_destroy_wrapper + 33 frame #15: 0xffffffff80d21c59 kernel`if_clone_destroyif_flags + 201 frame #16: 0xffffffff80d21b31 kernel`if_clone_destroy + 273 frame #17: 0xffffffff80d1f07f kernel`ifioctl + 1775 frame #18: 0xffffffff80c748fd kernel`kern_ioctl + 621 frame #19: 0xffffffff80c745e0 kernel`sys_ioctl + 256 frame #20: 0xffffffff810b289c kernel`amd64_syscall + 268 frame #21: 0xffffffff810897eb kernel`fast_syscall_common + 248 It's similar to what I've seen in similar PRs, but not exactly the same. --=20 You are receiving this mail because: You are the assignee for the bug.=
