Hello, well in further tests I had two more cases where it didn't boot like described before. During my last tests where 4-5 boots with version 2.6.8-4 worked flawlessly I had no AVM PCMCIA ISDN Fritzcard in my laptop. In the two cases where it didn't work again I had the AVM PCMCIA ISDN Fritzcard back in. But in a third case - directly afterwards - it still did work with the card plugged into the PCMCIA slot.
So this does not seem to be fixed completely. Its difficult to find a pattern in all of this. This how the AVM card is detected: Oct 15 21:59:11 localhost kernel: HiSax: Card 1 Protocol EDSS1 Id=HiSax (0) Oct 15 21:59:11 localhost kernel: HiSax: AVM A1 PCMCIA driver Rev. 2.9.2.5 Oct 15 21:59:11 localhost kernel: AVM A1 PCMCIA: io 0x140 irq 3 model 1 version 2 Oct 15 21:59:11 localhost kernel: AVM A1 PCMCIA: ISAC version (0): 2086/2186 V1.1 Oct 15 21:59:11 localhost kernel: AVM A1 PCMCIA: HSCX version A: V2.1 B: V2.1 Oct 15 21:59:11 localhost kernel: AVM A1 (PCMCIA): IRQ 3 count 2 Oct 15 21:59:11 localhost kernel: AVM A1 (PCMCIA): IRQ 3 count 6 Oct 15 21:59:11 localhost kernel: HiSax: DSS1 Rev. 2.32.2.3 Oct 15 21:59:11 localhost kernel: HiSax: 2 channels added Oct 15 21:59:11 localhost kernel: HiSax: MAX_WAITING_CALLS added Oct 15 21:59:11 localhost kernel: HiSax: if_command 6 called with invalid driverId 0!
