| |
Hi...
I _hate_ to do this, but I couldn't find (except for a reference to "others who have segfaults using glibc") no reference to this problem. Insmod of i2c, videodev and bttv succeed without problems or any message in /var/log/debug, messages or syslog.
Also, though I'm surely no expert, I tested a bit with gdb & such, and suspect there may be a problem that's not directly xawtv/bttv related.
Any suggestions?
John
