Hi, I have an ELSA Microlink PCI ISDN card, and i4b hangs when I boot. The card gets detected and shows: isic0: <ELSA QuickStep 1000pro PCI ISDN adapter> rev 0x01 int a irq 10 on pci0.11.0 isic0: IPAC PSB2115 Version 1.2 ...and the kernel continues to detect other devices. Later at the end (after npx0) before it is *supposed* to display i4b: ISDN call control device attached i4bctl: ISDN system control port attached i4brbch: 2 raw B channel access device(s) attached i4btrc: 1 ISDN trace device(s) attached ...it displays nothing, and locks up. I have DDB compiled in with debug kernel, but it locks up so hard, it won't even break with Ctl-Alt-Esc so sorry, no backtraces! SOLUTION: If I disconnect the ISDN cable during kernel boot, and then put it back when the system comes up into multiuser, i4b *does indeed* get attached and the card works beautifuly (that's how I sent this email) Card also works fine under Win2000 without these cable games so I think hardware can be ruled out. :( QUESTIONS: Is this a known problem? Am I the only one? What can I do to help? Does the card need to first be reset by i4b somehow? I'd love to hack around in the kernel, but without a backtrace or familiarity with i4b layer1 code, I don't know where to start. Tell me what I can do / where to start to debug this. Help! Without magical $5,000 robotic arm to disconnect and reconnect cable during boot, this is totally inadequate for a standalone server! ;-) SETUP: FreeBSD 3.4-RELEASE ELSA Microlink 1000 PCI ISDN Adapter i4b 0.83 with IPAC V1.2 patches posted on the list i4b 0.90 with IPAC V1.2 patches posted on the list, also no luck. P.S. I tried Fritz! AVM PCI and it works fine (i.e. don't need to play cable games.) Thanks, -Paul.
