Probably the low_latency bug again... this patch fixes a bunch of those including option: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=2400a2bfbd0e912193fe3b077f492d4980141813
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
my ZTE MF622 , if pluged and I am connect to internet. If I unplug lock the system. The patch mention in this bug have been applied on fedora kernels , stock 2.6.29 ?
Confirm the patch fixes things with a few different modems on F11. Can we get this pushed in an update?

Just tried with -198 build from koji. NetworkManager now is not able to connect to the network at all with my option card (see #507099 for the crash NetworkManager causes with the latest stable kernel).

Hi, I tried kernel-PAE-2.6.29.5-201.fc11.i686.rpm from koji and don't had any improvement , On my case when I unpluged usb 3G when connect to internet, X goes down and my laptop hangs, which don't happens on f10 or lower .

I also have kernel oops if I unplug the modem while connected to internet. In my case X don't goes down and if I re-plug the modem I can connect to internet. I'm on x64 and I'm using 2.6.29.6-211.fc11.x86_64 from koji.

However, there's also an NM bug that would cause NM to open the serial port more than once if you have a PIN set on the SIM. While the kernel certainly shouldn't panic here, it is something that's just been fixed in NM.

The main symptom is that an invalid kevent is created when the serial device is unplugged while a connection is active. Ports should be unregistered when device is disconnected, not when the parent usb_serial structure is deallocated. Each open file should hold a reference to the corresponding port structure, and the reference should be released when the file is closed. serial->disc_mutex should be acquired in serial_open(), to resolve the classic race between open and disconnect. serial_close() doesn't need to hold both serial->disc_mutex and port->mutex at the same time. Release the subdriver's module reference only after releasing all the other references, in case one of the release routines needs to invoke some code in the subdriver module. Replace a call to flush_scheduled_work() (which is prone to deadlocks) with cancel_work_sync(). Also, add a call to cancel_work_sync() in the disconnect routine. Reduce the scope of serial->disc_mutex in serial_disconnect(). The only place it really needs to protect is where the "disconnected" flag is set. This fixes the bug reported in http://bugs.freedesktop.org/show_bug.cgi?id=20703

Unfortunally with my modem (ONDA MT505UP) I still have the crash even with kernel 2.6.29.6-213.fc11.x86_64. If I remove the modem while connected to Internet all system hang and I can only poweroff my laptop. But I don't know if it's related with this bug....
kernel-2.6.29.6-213.fc11 has been pushed to the Fedora 11 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update kernel'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F11/FEDORA-2009-7617
Is this also supposed to be fixed in rawhide? I made a mistake and enabled repo rawhide instead of updates-testing, ended up with 2.6.31-0.67.rc2.git9.fc12.x86_64 kernel.

OK... retested with 2.6.29.6-213.fc11.x86_64, while connected to the internet the model gets lost at some point (i.e. as if I unplugged it from USB, but I did not), then gets automatically reattached. I am not sure if my issue is similar to what Fabio posted, I do not have a PIN set and I am not using NetworkManager as it does not recognize the modem most of the time, I am calling wvdial via gnome-ppp. I am pasting a little more than just the Oops, so you can see what happens before and after it.

kernel-2.6.29.6-213.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report.
(In reply to comment #22) > > With this new 2.6.29.6-213 from koji, yes. I had safely remove the modem while > connected to Internet. unfortunately just work on first time , on second crash again. Other thing, I have a 32-bit laptop and test it on i686 kernel. So I think is not all resolved. I got a oops on connect and remove usb, : option 2-2:1.2: device disconnected BUG: unable to handle kernel paging request at 00001028 IP: [<c063083b>] usb_kill_urb+0x27/0xa9 *pdpt = 0000000030481001 *pde = 000000004ddae067 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1d.0/usb2/idVendor Modules linked in: ppp_deflate zlib_deflate ppp_async crc_ccitt ppp_generic slhc fuse option usbserial usb_storage bridge stp llc bnep sco l2cap bluetooth sunrpc autofs4 lm90 hwmon i2c_i801 ipv6 cpufreq_ondemand acpi_cpufreq uinput snd_intel8x0 snd_intel8x0m snd_ac97_codec ac97_bus snd_pcm b44 ipw2200 snd_timer ssb mii snd firewire_ohci iTCO_wdt iTCO_vendor_support yenta_socket rsrc_nonstatic libipw firewire_core soundcore crc_itu_t lib80211 snd_page_alloc pcspkr wmi joydev serio_raw ata_generic pata_acpi i915 drm i2c_algo_bit i2c_core video output [last unloaded: scsi_wait_scan] Pid: 2545, comm: wvdial Not tainted (2.6.29.6-213.sb.fc11.i686.PAE #1) HP Compaq nx6110 (PY501EA#AB9) EIP: 0060:[<c063083b>] EFLAGS: 00010206 CPU: 0 EIP is at usb_kill_urb+0x27/0xa9 EAX: 00000000 EBX: 00001000 ECX: c08382d7 EDX: 00000232 ESI: ea050580 EDI: 00000002 EBP: f117be80 ESP: f117be64 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process wvdial (pid: 2545, ti=f117a000 task=ee1cf1a0 task.ti=f117a000) Stack: ec3fc1f8 ec3fc1c0 00000246 ea0c6818 f117be80 ea008c00 00000002 f117be9c f8337666 ea0c67e0 f0443c00 ea008c00 f833a6e4 ea0c67e0 f117bec4 f8325847 f117bec4 d68eec00 f833b864 f0443c00 ea008c54 f0443c00 00000000 00000000 Call Trace: [<f8337666>] ? option_close+0x98/0xaf [option] [<f8325847>] ? serial_close+0x7f/0x121 [usbserial] [<c05ca584>] ? tty_release_dev+0x146/0x3b7 [<c0446def>] ? remove_wait_queue+0x27/0x2c [<c04b2623>] ? vfs_ioctl+0x1d/0x76 [<c04b2f16>] ? do_vfs_ioctl+0x480/0x4ba [<c04a84c9>] ? rw_verify_area+0x9a/0xbb [<c05ca80c>] ? tty_release+0x17/0x21 [<c04a93c9>] ? __fput+0xce/0x15b [<c04a946e>] ? fput+0x18/0x1a [<c04a6a5d>] ? filp_close+0x56/0x60 [<c04a6adb>] ? sys_close+0x74/0xac [<c040945f>] ? sysenter_do_call+0x12/0x34 Code: 5b 5f 5d c3 55 89 e5 57 53 83 ec 14 0f 1f 44 00 00 ba 32 02 00 00 89 c3 b8 d7 82 83 c0 e8 d7 db df ff e8 3f 49 0e 00 85 db 74 7b <83> 7b 28 00 74 75 83 7b 2c 00 74 6f 3e ff 43 0c ba fe ff ff ff EIP: [<c063083b>] usb_kill_urb+0x27/0xa9 SS:ESP 0068:f117be64 ---[ end trace f87ab5489ad06cca ]---
I can confirm that the bug is unfortunately not fixed... I was connected to the internet via my Sierra AirCard 875U USB modem, suddenly the connection went down. In the log I could see that the modem was reattached and an oops. Note, that I did not physically disconnect the modem, so despite those "disconnected" and "new device" messages below - the modem has been physically connected to the usb port the whole time.

Hi ,testing with kernel 2.6.30.5-43.fc11.i686.PAE. I can't crash system anymore , I plug and unplug, USB 3G Modem, several times without any problem. Now, I think, I can say this issue is fixed. Thanks,
Same here with kernel 2.6.30.5-43.fc11 on x64. No more crash if I unplug the modem while I'm connected to Internet.
