[asterisk-users] debian/dahdi/zaphfc - Unable to receive TEI from network!
Hello, The harddisk of my etch/bristuffed asterisk1.2 box finally died. I moved the cheap (1397:2bd0) HFC-S card to a squeeze host (i686) and built dahdi modules 2.3.0.1 using m-a. After zaptel->dahdi and asterisk 1.2->1.6 config adaptations, everything seems ok, except for the BRI side, unable to bring layers 1/2 up. Asterisk reports: chan_dahdi.c:12393 dahdi_pri_error: 1 Unable to receive TEI from network! deskpro*CLI> pri show spans PRI span 1/0: Provisioned, Down, Active Of course, trying to dial out using the channel results in: app_dial.c: Unable to create channel of type 'DAHDI' (cause 34 - Circuit/channel congestion) I'm a little puzzled as to what's wrong, as I didn't change anything on the ISDN side compared to my very stable etch setup: same HFC-S card working in TE-mode, same bri_cpe_ptmp signalling, same NT1, I even reused the same cable. I tried the force_l1_up=1 kmod parameter, without seeing any change. I tried using fcshdlc instead of hardhdlc with no luck. I even swapped the NT1 with a new one, also without result. Any pointers on how to debug this TEI assignment problem are welcome. I have an plain ISDN phone that's also connected to the NT1's S-bus which works fine. I can swap the cables between the phone and HFC-S card or disconnect the phone, it doesn't change anything. OS-level and asterisk-level stuff looks as per my expectations (which may be misguided...). The only strange thing is the warn_slowpath_common warning when loading zaphfc module, but I'm not sure whether this is relevant as people seem to have a working setup despite seeing this warning. Can anyone confirm that this is not relevant? I include some info on my setup below. I can also provide config files for the previously running etch/asterisk1.2 setup, if requested. Thanks for any help alex -------------------- (I filtered out stuff that's IMHO non-relevant) # dmesg [ 7.795103] WARNING: at /usr/src/modules/dahdi/drivers/dahdi/dahdi-base.c:5866 dahdi_register+0x39/0x296 [dahdi]() [ 7.795110] Hardware name: Deskpro [ 7.795115] Modules linked in: zaphfc(+) dahdi snd_intel8x0(+) snd_ac97_codec ac97_bus crc_ccitt snd_pcm snd_timer parport_pc i2c_i801 snd shpchp parport soundcore processor button pcspkr evdev i2c_core pci_hotplug snd_page_alloc rng_core ext3 jbd mbcache dm_mod raid1 md_mod sd_mod crc_t10dif ata_generic uhci_hcd ata_piix ehci_hcd e100 libata usbcore thermal floppy mii nls_base scsi_mod thermal_sys [last unloaded: scsi_wait_scan] [ 7.795201] Pid: 429, comm: modprobe Not tainted 2.6.32-5-686 #1 [ 7.795207] Call Trace: [ 7.795231] [<c103014d>] ? warn_slowpath_common+0x5e/0x8a [ 7.795241] [<c1030183>] ? warn_slowpath_null+0xa/0xc [ 7.795252] [<e0d48d47>] ? dahdi_register+0x39/0x296 [dahdi] [ 7.795275] [<c126b4e3>] ? printk+0xe/0x13 [ 7.795296] [<e0d7bc34>] ? hfc_probe+0x8db/0xb64 [zaphfc] [ 7.795309] [<e0d7bd1c>] ? hfc_probe+0x9c3/0xb64 [zaphfc] [ 7.795334] [<c1145895>] ? local_pci_probe+0xb/0xc [ 7.795343] [<c11461df>] ? pci_device_probe+0x41/0x63 [ 7.795359] [<c11b2306>] ? driver_probe_device+0x8a/0x11e [ 7.795368] [<c11b23da>] ? __driver_attach+0x40/0x5b [ 7.795378] [<c11b1d49>] ? bus_for_each_dev+0x37/0x5f [ 7.795386] [<c11b21d9>] ? driver_attach+0x11/0x13 [ 7.795395] [<c11b239a>] ? __driver_attach+0x0/0x5b [ 7.795403] [<c11b1811>] ? bus_add_driver+0x99/0x1c5 [ 7.795412] [<c11b260b>] ? driver_register+0x87/0xe0 [ 7.795422] [<c10e8e5f>] ? proc_register+0xf8/0x142 [ 7.795431] [<c11463b0>] ? __pci_register_driver+0x33/0x89 [ 7.795442] [<e0d7f000>] ? hfc_init_module+0x0/0x30 [zaphfc] [ 7.795451] [<c100113e>] ? do_one_initcall+0x55/0x155 [ 7.795461] [<c1057135>] ? sys_init_module+0xa7/0x1d7 [ 7.795475] [<c10030fb>] ? sysenter_do_call+0x12/0x28 [ 7.795482] ---[ end trace c3edff8cea26edee ]--- [ 7.799466] vzaphfc: card 0: resetting [ 7.816194] vzaphfc: card 0 configured for TE mode at mem 0x40100000 (0xe0d84000) IRQ 18 ...
