Public bug reported: Binary package hint: linux-image
System: Xubuntu 8.10, x86-64 generic/desktop Hardware: Core2 Duo (Lenovo Thinkpad T400, US model 2764-CTO) Kernel: 2.6.27 (-9, -10, -11) When rebooting or shutting down, I consistently get the following crash dump (like kernel oops?) when the shutdown sequence reaches /etc/rc0.d/S20sendsigs . A series of screenshots is available here (sorry no plain text since the output is printed seemingly after syslog or other logging has stopped): http://www.flickr.com/photos/wirawan0/3239832727/in/set-72157613138397091/ (These bug screenshot photos are for everybody to use; they are intended to be public domain.) The first few lines of the crash dump are like this: iwlagn: Error: response NULL in 'REPLY_ADD_STA' BUG: unable to handle kernel paging request at ffff8800ffff8880 IP: [<ffffffff80501ea2>] schedule_timeout+0xa2/0xd0 PGD 202063 PUD 0 Oops: 0000 [1] SMP CPU 0 Modules linked in: nls_iso8859_1 nsl_cp437 vfat fat aes_x86_64 aes_generic ecryptfs af_packet i915 drm bridge rfcomm stp bnep scp l2cap bluetooth ppdev acpi_cpufreq cpufreq_ondemand cpufreq_conservative cpufreq_stats freq_table cpufreq_userspace cpufreq_powersave pci_slot sbs sbshc container ipv6 iptable_filter ip_tables x_tables sbp2 parport_pc lp parport loop usb_storage libusual .... (more modules linked in are not printed here) Then scrolling below: Pid: 5611, comm: NetworkManager Not tainted 2.6.27-11-generic #1 ... What's strange is this: I have been in contact with another T400 owner (UK model) and he also installed xubuntu 8.10 64-bit on his and he did not have this kind of problem. Does anybody else experience the same kind of problem? After the crash above, the reboot/shutdown would not continue. Often I have to hold the power button to make it turn off. Some workarounds: * rmmod iwlagn before rebooting/shutting down -- then there is no such issue * or, disable the wireless with the hardware button -- then the shutdown/restart went smoothly Wirawan ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: New -- iwlagn driver crashes on reboot/shutdown on Thinkpad T400 https://bugs.launchpad.net/bugs/325426 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
