Date: Sat, 05 Jun 2010 10:53:51 +0200 From: "Alexander Fischer" <linux-kernel@...nungsdienst.org> To: "Linux-Kernel Mailing List" <linux-kernel@...r.kernel.org> Subject: Kernel freeze with Umts-stick Hello, A minute after i establish a connection to the internet with my UMTS data stick, i receive a kernel stack trace and the system freezes. Hardware is an Globetrotter HSUPA Modem with 7501 Option Chip. System is: Slackware-13.1 with vanilla kernel 2.6.34 I'd like to give further information, so somebody is able to fix it, but so far i do not know, what is relevant in that case. The syslog message is: Jun 5 09:39:00 darkstar kernel: BUG: scheduling while atomic: swapper/0/0x10010100 Jun 5 09:39:00 darkstar kernel: Modules linked in: ppp_deflate bsd_comp ppp_async ipv6 ppp_generic slhc usb_storage hso snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss rfcomm sco bridge stp llc bnep l2cap cpufreq_ondemand speedstep_lib acpi_cpufreq freq_table lp ppdev parport_pc parport fuse snd_hda_codec_realtek rt2860sta(C) rt2800pci rt2800lib snd_hda_intel rt2x00usb rt2x00pci snd_hda_codec crc_ccitt rt2x00lib i915 snd_hwdep snd_pcm drm_kms_helper snd_timer mac80211 uvcvideo rtc_cmos snd drm cfg80211 eeepc_laptop videodev rtc_core intel_agp soundcore btusb i2c_algo_bit agpgart processor bluetooth snd_page_alloc video psmouse eeprom_93cx6 v4l1_compat thermal atl1e i2c_i801 thermal_sys sparse_keymap rtc_lib sg rfkill battery ac serio_raw i2c_core led_class output button evdev hwmon usbhid hid uhci_hcd ehci_hcd ext4 jbd2 ext2 mbcache Jun 5 09:39:00 darkstar kernel: Modules linked in: ppp_deflate bsd_comp ppp_async ipv6 ppp_generic slhc usb_storage hso snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss rfcomm sco bridge stp llc bnep l2cap cpufreq_ondemand speedstep_lib acpi_cpufreq freq_table lp ppdev parport_pc parport fuse snd_hda_codec_realtek rt2860sta(C) rt2800pci rt2800lib snd_hda_intel rt2x00usb rt2x00pci snd_hda_codec crc_ccitt rt2x00lib i915 snd_hwdep snd_pcm drm_kms_helper snd_timer mac80211 uvcvideo rtc_cmos snd drm cfg80211 eeepc_laptop videodev rtc_core intel_agp soundcore btusb i2c_algo_bit agpgart processor bluetooth snd_page_alloc video psmouse eeprom_93cx6 v4l1_compat thermal atl1e i2c_i801 thermal_sys sparse_keymap rtc_lib sg rfkill battery ac serio_raw i2c_core led_class output button evdev hwmon usbhid hid uhci_hcd ehci_hcd ext4 jbd2 ext2 mbcache Jun 5 09:39:00 darkstar kernel: Jun 5 09:39:00 darkstar kernel: Pid: 0, comm: swapper Tainted: G C 2.6.34-smp #1 901/901 Jun 5 09:39:00 darkstar kernel: EIP: 0060:[<c1086ea0>] EFLAGS: 00000246 CPU: 0 Jun 5 09:39:00 darkstar kernel: EIP is at rcu_bh_qs+0x0/0x30 Jun 5 09:39:00 darkstar kernel: EAX: 00000000 EBX: 00000001 ECX: c1545a18 EDX: 00000000 Jun 5 09:39:00 darkstar kernel: ESI: 00000018 EDI: 00000006 EBP: c1541ecc ESP: c1541e88 Jun 5 09:39:00 darkstar kernel: DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Jun 5 09:39:00 darkstar kernel: Process swapper (pid: 0, ti=c1540000 task=c156eba0 task.ti=c1540000) Jun 5 09:39:00 darkstar kernel: Stack: Jun 5 09:39:00 darkstar kernel: c1042897 00000001 c1541ec0 c108391c c1546700 c1541ec0 c101d41f c1545a18 Jun 5 09:39:00 darkstar kernel: <0> c105dc7d 00000017 0000000a 00000000 c1622880 00000100 00000046 00000000 Jun 5 09:39:00 darkstar kernel: <0> 00000017 c1541ed8 c10429b5 00000079 c1541ee0 c1042b25 c1541f0c c13faa35 Jun 5 09:39:00 darkstar kernel: Call Trace: Jun 5 09:39:00 darkstar kernel: [<c1042897>] ?
