-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been trying to get the modem in my Acer Aspire 5315 laptop working and I've made it to the point where I can load agrmodem and agrserial and get /dev/ttyAGRS3 to come up. When I try to open the port in minicom tho minicom just hangs and can't be killed. A look in dmesg shows this [ 133.859509] * Hello Agere Driver ** [ 133.859549] usbcore: registered new interface driver agr12dec2006 [ 136.411331] Loading module Agere Modem Controller driver version 2.1.80 (2007-10-01) [ 136.411335] Disabling lock debugging due to kernel taint [ 205.540229] ACPI: EC: GPE storm detected, transactions will use polling mode [ 206.861387] serial8250_register_ports: BaseAddress 0x0004 Irq 22 [ 206.861398] ttyAGS3 at I/O 0x4 (irq = 22) is a AgereModem [ 206.863094] agrserial - ret_val 0, call: lt_modem_ops.init_modem [ 206.863103] Loading module Agere Modem Interface driver version 2.1.80.0 (2007-10-01) [ 236.833804] ==> codecType = 0x32 [ 236.833814] BUG: unable to handle kernel NULL pointer dereference at 00000033 [ 236.833820] IP: [<fd37e1ef>] azlGetResourceInformation+0x13/0x3f [agrmodem] [ 236.833873] *pde = 00000000 [ 236.833876] Oops: 0000 [#1] SMP [ 236.833880] last sysfs file: /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq [ 236.833883] Modules linked in: agrserial agrmodem coretemp [ 236.833889] [ 236.833893] Pid: 6252, comm: minicom Tainted: P 2.6.34-gentoo-r12 #3 Acadia /Aspire 5315 [ 236.833896] EIP: 0060:[<fd37e1ef>] EFLAGS: 00210246 CPU: 0 [ 236.833943] EIP is at azlGetResourceInformation+0x13/0x3f [agrmodem] [ 236.833946] EAX: f6828400 EBX: f84040c4 ECX: 00000003 EDX: 00000000 [ 236.833948] ESI: f84040c4 EDI: f8404028 EBP: f393bcdc ESP: f393bcdc [ 236.833951] DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 [ 236.833955] Process minicom (pid: 6252, ti=f393a000 task=f3a072a0 task.ti=f393a000) [ 236.833957] Stack: [ 236.833959] f393bcfc fd369179 f840e5e9 f840e5ea f393bcfc c143f0a5 fd3975ea f393bd4b [ 236.833965] <0> f393bd6c fd352401 f84040c4 f801f048 00000008 00000001 f840439c 00000004 [ 236.833972] <0> c16b6a00 000080d0 00000000 00000000 f393bda4 c108b321 c16b73c0 00000001 [ 236.833980] Call Trace: [ 236.834040] [<fd369179>] ?
