It seems you are replying to a very old original message. Since that message was sent, linux-wireless@vger.kernel.org has become the primary forum for wireless discussion. Any chance you are savvy enough with git to try the wireless-dev kernel? git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-dev.git Can you replicate the problem using those sources? If so, you may want to attach your .config in your reply (just in case the exact config makes a difference). Thanks, John -- John W.

If so, you may > want to attach your .config in your reply (just in case the exact > config makes a difference). Yes I can, except the "reproducibilty" reduces a bit. It's fairly easy to reproduce though. The config will go on annex. I've found out one interesting thing: if I modprobe -r the iwl3945 module while wpa_supplicant is running it doesn't trigger a hang like on bcm (original message). On the contrary, it prevents a hang if then I modprobe iwl3945 again and kill wpa_supplicant. One time I managed to get the kernel to spit out something, but it was on the gentoo kernel. I hope this is relevant, there was no hang when this was spit out: ------------[ cut here ]------------ kernel BUG at kernel/workqueue.c:258! invalid opcode: 0000 [1] SMP CPU 1 Modules linked in:<7>wlan0: Trigger new scan to find an IBSS to join iwl3945 mac80211<3>iwl3945: U iwl_scan_initiate Starting scan... cfg80211 rfcomm l2cap snd_pcm_oss snd_mixer_oss snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device acpi_cpufreq asus_laptop nvidia(P) i2c_core snd_hda_intel snd_pcm snd_timer snd snd_page_alloc yenta_socket rsrc_nonstatic pcmcia_core sdhci mmc_core hci_usb bluetooth tpm_infineon gspca Pid: 2660, comm: iwl3945 Tainted: P 2.6.22-gentoo #1 RIP: 0010:[<ffffffff8023df87>] [<ffffffff8023df87>] run_workqueue+0x73/0x10b RSP: 0018:ffff8100747fded0 EFLAGS: 00010207 RAX: 0000000000000000 RBX: ffff810074fb1d40 RCX: ffff8100748f19d0 RDX: ffff8100748f19d0 RSI: ffff8100747fdef0 RDI: ffff8100748f19c8 RBP: ffffffff880bf3a2 R08: ffff8100747fc000 R09: ffff8100740679d8 R10: 0000000000000000 R11: ffffffff8043d14e R12: ffff81007407bbd0 R13: ffffffffffffffff R14: ffffffff806445a0 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff81007ff00f40(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 000000000060e788 CR3: 0000000074679000 CR4: 00000000000006e0 Process iwl3945 (pid: 2660, threadinfo ffff8100747fc000, task ffff81007f4daf60) Stack: ffff810074fb1d40 ffff810074fb1d40 ffffffff8023e7ff ffffffff8023e8d9 0000000000000000 ffff81007f4daf60 ffffffff802415f0 ffff8100747fdf08 ffff8100747fdf08 0000000000000000 ffff810074fb1d40 ffffffff802414de Call Trace: [<ffffffff8023e7ff>] worker_thread+0x0/0xe4 [<ffffffff8023e8d9>] worker_thread+0xda/0xe4 [<ffffffff802415f0>] autoremove_wake_function+0x0/0x2e [<ffffffff802414de>] kthread+0x47/0x75 [<ffffffff8020a3b8>] child_rip+0xa/0x12 [<ffffffff80241497>] kthread+0x0/0x75 [<ffffffff8020a3ae>] child_rip+0x0/0x12 Code: 0f 0b eb fe f0 0f ba 71 f8 00 ff d5 65 48 8b 04 25 10 00 00 RIP [<ffffffff8023df87>] run_workqueue+0x73/0x10b RSP <ffff8100747fded0> > Thanks, > > John > -- > John W.

I've applied the patch and tortured the system as far as I could, and no hang at all :) I've read the thread and it apparently replaces one bad problem for a lesser one, so I understand if it's not applied.. But at least there is a place in the code to point as the culprit :) Thanks, Renato Caldas ^ permalink raw reply [flat|nested] 6+ messages in thread

That's my fault, I missed that patch. If everybody put [PATCH] to subject of mails containing a patch... (sigh) > John: This is about the patch in the "mac80211/bcm43xx deadlock" thread > from Michael, it kills some rtnl_lock()/unlock() that causes this > deadlock. Yes, please apply (the patch is below). Of course, we'll need a proper fix but until it is ready this should be applied to prevent deadlocks. Thanks, Jiri --- Subject: [PATCH] mac80211: remove rtnl locking in ieee80211_sta.c From: Michael Wu <flamingice@sourmilk.net> The rtnl is held in ieee80211_sta.c to prevent some potential races with userspace. Unfortunately, it also has the potential for deadlocks on interface down. This patch removes the rtnl locking to eliminate the deadlocks.
