Hi, I have a Fedora 7 xen system with a domU to which I have delegated via pciback two isdn pci cards. One is a HFC-S card, the other a AVM Fritz!Card Pci 2.0. In the domU I load mISDN drivers for the cards. The two cards are recognized and function well UNTIL I either decide to unload one or both of the card driver modules (hfcpci and avmfritz) or I decide to shut down the domU. At this point the WHOLE system locks up: the mouse in Gnome reacts as if in slow-motion, typing in a already open terminal window does still work if characters are entered deliberately slowly one by one. However, commands are no longer executed. Occasionally, not always however, a message is output along the lines of: irq 22: nobody cared (try booting with the "irqpoll" option) Obviously the advise given by the error message did not help... I did some experiments: all the modules misdn loads when executing "/etc/init.d/misdn-init start" unload flawlessly if no cards are defined in /etc/misdn-init.conf. It is only the actual driver modules for the cards that evoke the problem. Both modules, avmfritz (for the AVM Fritz!Card Pci 2.0) and hfcpci (for the Cologne HFC-S card) cause the system to lock up. It thus seems to me to be a systematic problem with my setup rather than a problem with the implementation with one of the drivers. Is this a known issue? Is there a remedy? How should I go about debugging it? I would be grateful for any hints.

Hi, i recently had the same issues with ISDN pci devices. running Xen 3.1 with Ubuntu Feisty as Dom0 and Ubuntu Dapper as domU My current setup now works without problems after I changed the boot entry in /boot/grub/menu.lst to title Xen 3.1-i386-pae / Ubuntu, kernel 2.6.20-100-server root (hd0,1) kernel /xen-3.1-i386-pae.gz module /vmlinuz-2.6.20-100-server root=UUID=09503299-c560-45de-b69d-8d98eadc7b23 ro console=tty0 irq=poll pciback.hide=(03:01.0) module /initrd.img-2.6.20-100-server quiet savedefault without the irq=poll option, the system showed unpredictable failures after unloading the ISDN driver and/or shutting down the domU. this particular domU runs kernel 2.6.19-4-server (ubuntu repo) Arik Raffael Funke schrieb:> Hi, > > I have a Fedora 7 xen system with a domU to which I have delegated via > pciback two isdn pci cards.

Hi, I suppose only the "irq=poll" kernel argument is the one that matters, right? I tried it, both in my dom0 and domU, but when I unload my misdn drivers in the domU everything still locks up. You have the irq=poll apparently for the dom0. Where are you loading the mISDN drivers, also in dom0. If I load/unload the drivers in dom0, I have no problem what-so-ever. Only if I unload the drivers in a domU, the whole system freezes.
