Marvin/All, I can only confirm that the problem does exist as reported by other users of the modem. http://forum.ubuntu.ru/index.php?topic=74024.msg610543#msg610543 The site is in Russian. Briefly, these guys are using Ubuntu 9.10 with the kernel 2.6.31-17. The driver compiles and loads fine, but produces the same Null pointer problem: <<< [ 307.576111] BUG: unable to handle kernel NULL pointer dereference at 00000060 [ 307.576121] IP: [<e1033498>] ResumeCallBack+0x18/0x34 [agrmodem] [ 307.576174] *pde = 1711d067 *pte = 00000000 [ 307.576179] Oops: 0000 [#1] SMP [ 307.576182] last sysfs file: /sys/devices/virtual/tty/ttyAGS3/dev [ 307.576186] Modules linked in: agrserial agrmodem binfmt_misc ppdev snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep arc4 snd_pcm_oss snd_mixer_oss snd_pcm ecb snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi snd_seq_midi_event pcmcia snd_seq snd_timer iptable_filter rt73usb snd_seq_device yenta_socket ip_tables crc_itu_t joydev rsrc_nonstatic sdhci_pci x_tables rt2x00usb snd pcmcia_core sdhci rt2x00lib soundcore led_class snd_page_alloc input_polldev psmouse mac80211 cfg80211 serio_raw lp parport usbhid fbcon tileblit font bitblit softcursor 8139too 8139cp mii ohci1394 ieee1394 i915 drm i2c_algo_bit video output intel_agp agpgart >>> The modem and the driver are reported to work fine under Ubuntu 9.04 (with kernel version < 2.6.31, I guess). So, it does look like the conflict exists between different modules/resources/interrupts. The Bootup.txt file produced by scanModem suggests the following: <<< 9) Get unloading.gz from http://linmodems.technion.ac.il/linmodems/ This script unloads excess drivers which may be competing for resources. Before trying to set up the modem, do: $ gunzip unloading.gz $ chmod +x unloading $ su - root # ./unloading Or for Ubuntu related Distros $ sudo ./unloading >>> Actually, the correct link to the script is this: http://linmodems.technion.ac.il/packages/unloading.gz I am not sure, maybe this script is worth trying. -- Nick Zhuravlev www.auriga.com On Sat, Jan 16, 2010 at 06:07:31PM -0500, Marvin Stodolsky <marvin.stodolsky@xxxxxxxxx> wrote: > Eddy, > > You are correctly using the only available drives for the 11c11040 > modem chip hosted on the HDA card. > > But this is bad System news > ----------------------------------------------- > [ 213.036277] Oops: 0000 [#1] SMP > [ 213.036286] last sysfs file: /sys/devices/virtual/tty/ttyAGS3/dev > [ 213.036293] Modules linked in: agrserial agrmodem etc > ---------------------------------------------- > Try shutting as much other software as possible.
