Hello Jeroen and other readers on the list(s), 2 days ago I had send a message to the linux-hams list and to the SuSE Ham lists. It appeared on SuSE's lists, but not on this list - most likely because seconds before I subscribed. Anyway, I reported a complete hangup when using FBB with the SuSE 7.3 2.4.10 kernel. With a suggestion of Jean-Paul I could find the 2.2.19 kernel on the SuSE CD which works fine as bypass. But I still want to run the new kernel. I fetched the latest kernel from SuSE, 2.4.14-SUSE (which is the 2.4.14 kernel from http://www.kernel.org plus SuSE's patches as available on ftp://ftp.suse.com/pub/people/mantel/next/). This version of kernel and modules still freezes the system when I start FBB. Traces I added to FBB showed that it happens just after FBB has send its beacons. Note that my system also freezes with other programs, but not as fast as FBB did... I like to stress that this is not an FBB problem. After this I applied your 2 patches. It looks like now the system stays up! At least is didn't crash instantly anymore - of course I did not run any stress-tests obviously, but is sure looks good! Kind regards, Henk.
