Message-Id: <201007261710.38000.thomas@m3y3r.de> Date: Mon, 26 Jul 2010 17:10:37 +0200 From: Thomas Meyer <thomas@...3r.de> To: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: 2.6.35-rc6: S2R hangs + WARNING: at net/mac80211/scan.c config can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=15673 1.) suspend to ram very often does not work in 2.6.35-rc6 (but sometimes it does work!). S2R very often results in a black screen with backlight on. a dmesg of a successful S2R cycle can be found in above bug report. this is a regression against 2.6.34.x that did survive tens of S2R cycles. 2.) Also I found this in dmesg: [16150.615478] ------------[ cut here ]------------ [16150.615511] WARNING: at net/mac80211/scan.c:262 ieee80211_scan_completed+0x10c/0x190 [mac80211]() [16150.615516] Hardware name: Aspire 1810T [16150.615520] Modules linked in: tcp_lp fuse cpufreq_ondemand acpi_cpufreq mperf ip6t_REJECT nf_conntrack_ipv6 ip6table_filter ip6_tables ipv6 kvm_intel kvm uinput arc4 ecb snd_hda_codec_intelhdmi snd_hda_codec_realtek snd_hda_intel iwlagn iwlcore snd_hda_codec snd_hwdep mac80211 snd_seq snd_seq_device snd_pcm snd_timer cfg80211 snd iTCO_wdt iTCO_vendor_support uvcvideo soundcore rfkill pcspkr wmi videodev v4l1_compat serio_raw joydev snd_page_alloc i2c_i801 sha256_generic aes_i586 aes_generic cbc dm_crypt [last unloaded: scsi_wait_scan] [16150.615593] Pid: 870, comm: iwlagn Tainted: G I 2.6.35-rc6 #112 [16150.615598] Call Trace: [16150.615614] [<c0430e42>] warn_slowpath_common+0x72/0xa0 [16150.615631] [<f9b06eac>] ? ieee80211_scan_completed+0x10c/0x190 [mac80211] [16150.615648] [<f9b06eac>] ? ieee80211_scan_completed+0x10c/0x190 [mac80211] [16150.615657] [<c0430e92>] warn_slowpath_null+0x22/0x30 [16150.615673] [<f9b06eac>] ieee80211_scan_completed+0x10c/0x190 [mac80211] [16150.615694] [<f9bc3b44>] iwl_bg_scan_completed+0xd4/0x1b0 [iwlcore] [16150.615704] [<c0445fd3>] worker_thread+0xf3/0x1f0 [16150.615713] [<c042c492>] ? finish_task_switch.clone.0+0x32/0xa0 [16150.615731] [<f9bc3a70>] ? iwl_bg_scan_completed+0x0/0x1b0 [iwlcore] [16150.615740] [<c0449900>] ? autoremove_wake_function+0x0/0x40 [16150.615748] [<c0445ee0>] ? worker_thread+0x0/0x1f0 [16150.615755] [<c0449504>] kthread+0x74/0x80 [16150.615762] [<c0449490>] ? kthread+0x0/0x80 [16150.615770] [<c040347e>] kernel_thread_helper+0x6/0x10 [16150.615775] ---[ end trace a7919e7f17c0a727 ]--- [16150.615779] ------------[ cut here ]------------ [16150.615797] WARNING: at net/mac80211/scan.c:265 ieee80211_scan_completed+0x181/0x190 [mac80211]() [16150.615802] Hardware name: Aspire 1810T [16150.615805] Modules linked in: tcp_lp fuse cpufreq_ondemand acpi_cpufreq mperf ip6t_REJECT nf_conntrack_ipv6 ip6table_filter ip6_tables ipv6 kvm_intel kvm uinput arc4 ecb snd_hda_codec_intelhdmi snd_hda_codec_realtek snd_hda_intel iwlagn iwlcore snd_hda_codec snd_hwdep mac80211 snd_seq snd_seq_device snd_pcm snd_timer cfg80211 snd iTCO_wdt iTCO_vendor_support uvcvideo soundcore rfkill pcspkr wmi videodev v4l1_compat serio_raw joydev snd_page_alloc i2c_i801 sha256_generic aes_i586 aes_generic cbc dm_crypt [last unloaded: scsi_wait_scan] [16150.615871] Pid: 870, comm: iwlagn Tainted: G W I 2.6.35-rc6 #112 [16150.615875] Call Trace: [16150.615884] [<c0430e42>] warn_slowpath_common+0x72/0xa0 [16150.615901] [<f9b06f21>] ? ieee80211_scan_completed+0x181/0x190 [mac80211] [16150.615916] [<f9b06f21>] ? ieee80211_scan_completed+0x181/0x190 [mac80211] [16150.615925] [<c0430e92>] warn_slowpath_null+0x22/0x30 [16150.615941] [<f9b06f21>] ieee80211_scan_completed+0x181/0x190 [mac80211] [16150.615959] [<f9bc3b44>] iwl_bg_scan_completed+0xd4/0x1b0 [iwlcore] [16150.615968] [<c0445fd3>] worker_thread+0xf3/0x1f0 [16150.615976] [<c042c492>] ? finish_task_switch.clone.0+0x32/0xa0 [16150.615995] [<f9bc3a70>] ? iwl_bg_scan_completed+0x0/0x1b0 [iwlcore] [16150.616003] [<c0449900>] ? autoremove_wake_function+0x0/0x40 [16150.616011] [<c0445ee0>] ? worker_thread+0x0/0x1f0 [16150.616018] [<c0449504>] kthread+0x74/0x80 [16150.616024] [<c0449490>] ? kthread+0x0/0x80 [16150.616031] [<c040347e>] kernel_thread_helper+0x6/0x10 [16150.616037] ---[ end trace a7919e7f17c0a728 ]--- [17435.271312] npviewer.bin[3805]: segfault at b492e04c ip b6ffb057 sp bff1be60 error 4 in libflashplayer.so[b6c5c000+b04000] -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
