Shaji There are three (at least) different agrsm code packages, for the various Agere chipsets. Please run scanModem and send us the ModemData.txt output, to more precisely identify your chipset. There are alternate ALSA drivers for some Agere/LSI chipsets. Which code package did you use to compile your driver?? An alternative may evade your problem: [ 989.115533] Loading module Agere Modem Interface driver version 2.1.80.0 (2007-10-01) [ 1043.645147] ==> codecType = 0x32 [ 1043.645196] BUG: unable to handle kernel NULL pointer dereference at 0000003c etc. MarvS scanModem maintainer On Wed, Oct 21, 2009 at 1:38 PM, <webkitdev@xxxxxxx> wrote: > Thanks Jacques. > > Using wvdial, I am getting a kernel OOPS.. will look at this more closely .. > > Shaji > > [ 981.902086] * Hello Agere Driver ** > [ 981.902158] usbcore: registered new interface driver agr12dec2006 > [ 984.510433] Loading module Agere Modem Controller driver version 2.1.80 > (2007-10-01) > [ 989.115374] ttyAGS3 at I/O 0x400 (irq = 18) is a AgereModem > [ 989.115533] Loading module Agere Modem Interface driver version 2.1.80.0 > (2007-10-01) > [ 1043.645147] ==> codecType = 0x32 > [ 1043.645196] BUG: unable to handle kernel NULL pointer dereference at > 0000003c > [ 1043.645210] IP: [<fb959868>] setResumeCallBack+0x8/0x20 [agrmodem] > [ 1043.645324] *pde = 00000000 > [ 1043.645333] Oops: 0000 [#1] SMP > [ 1043.645342] last sysfs file: > /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT1/voltage_n > ow > [ 1043.645352] Modules linked in: agrserial agrmodem binfmt_misc ppdev > bridge stp bnep snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep > snd_pcm_oss arc4 ecb btusb snd_mixer_oss ath5k snd_pcm snd_seq_dummy > mac80211 snd_seq_oss snd_seq_midi ath iptable_filter uvcvideo snd_rawmidi > joydev snd_seq_midi_event dm_crypt ip_tables x_tables videodev v4l1_compat > snd_seq k8temp acer_wmi snd_timer snd_seq_device sdhci_pci sdhci led_class > cfg80211 ricoh_mmc snd i2c_nforce2 nvidia(P) agpgart soundcore > snd_page_alloc psmouse serio_raw lp parport ohci1394 ieee1394 video output > forcedeth > [ 1043.645465] > [ 1043.645476] Pid: 2796, comm: cp Tainted: P (2.6.31-13-generic > #45-Ubuntu) Aspire 4520 > [ 1043.645486] EIP: 0060:[<fb959868>] EFLAGS: 00010246 CPU: 1 > [ 1043.645565] EIP is at setResumeCallBack+0x8/0x20 [agrmodem] > [ 1043.645573] EAX: 00000000 EBX: f81bc0c4 ECX: f6a27500 EDX: 00000000 > [ 1043.645580] ESI: f81bc0c4 EDI: f81bc028 EBP: f67e9d00 ESP: f67e9d00 > [ 1043.645587] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 > [ 1043.645596] Process cp (pid: 2796, ti=f67e8000 task=f69657f0 > task.ti=f67e8000) > [ 1043.645601] Stack: > [ 1043.645606] f67e9d20 fb944765 fb929470 f81c65ea f67e9d20 c056a25e > fb972c73 f67e9d6f > [ 1043.645624] <0> f67e9d90 fb92d9e1 f81bc0c4 f8121048 00000008 00000001 > f81bc39c 00000004 > [ 1043.645641] <0> c15e4120 00000000 c077dd60 00000000 c01b468d 00000001 > 00000041 ffffffff > [ 1043.645661] Call Trace: > [ 1043.645756] [<fb944765>] ?
