http://bugzilla.novell.com/show_bug.cgi?id=541736 Summary: ISDN: connection breaks when adding second channel/link (slave-device) Classification: openSUSE Product: openSUSE 11.2 Version: Milestone 6 Platform: x86 OS/Version: Linux Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: schaefer.frank@gmx.net QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.1.3) Gecko/20090909 SUSE/3.5.3-1.2 Firefox/3.5.3 When I activate B-channel-bundling, the data-rate drops to ~0 and host are no longer reachable. When I remove the second link, everything is fine again. I checked DNS, Gateway and routing table and they don't change, but ping doesn't work any more. It even doesn't tell me that the host is unreachable, it just blocks. A small amount of data (~500 bytes/sec) seems to be transferred while it is running. 100% package loss displayed after Ctrl-C. The problem seems to be introduced somewhere between kernel 2.6.27.29 and 2.6.28.10. I'm quite sure this is not a ISDN-configuration problem, because openSUSE 11.1 with 2.6.27 works but when I boot the the same system with the same configuration into a vanilla kernel > 2.6.27, it stops working. The same now with openSUSE 11.2. AFAICS, ifup/ifdown is used for ISDN-connections and channel-bundling is done with a network slave device-configuration, so I assume the reason is located in the network-system. Used hardware is a HFC-S-PCI-card (Asus 0675) configured with YaST (Hisax-driver). If you need further informations/investigations, just tell me.
