I have put the following information at: http://www.wh8.tu-dresden.de/fddi/ * My .config for 2.4.22-pre6 * dmesg output of 2.4.22-pre6 (both 2.4.21 and 2.4.22-pre6 behave the same) * the ksymoops output of the lockup * the output of lspci -v * the fddi patch i used (applies cleanly to 2.4.21 and with fuzz to -pre6) Note that the fddi patch includes a patch you've previously sent me, which isn't present in the driver on your website. If you need more information, let me know. Also if you have any tips or patches that would help in debugging the issue, I'm happy to try them. MT> What makes you believe this? There is no matching code sequence like the MT> one from your dump in the driver, to be exact: in a driver compiled with MT> gcc 3.3 and kernel 2.4.21. The fact that the backtrace in the decoded oops looks like the lockup happened in the fddi driver led me to the conclusion that this may be the culprit. I have compiled the 2.4.22-pre6 kernel with gcc-3.3 also.
