Oops with 2.4.0-test8/Token Ring/Netscape
Hello *, this is a bug report about an Oops I get sometimes with kernel 2.4.0-test8; usually it is triggered by reading newsgroups in Netscape 4.75. I know Netscape is not quite bugfree yet, but at least it shouldn't be allowed to do something this bad. I'm using SuSE 7.0 on a ThinkPad 600X (2645-4EU), with a 500MHz Pentium III, 192M RAM (191M usable -- the int15/e820 memory detection doesn't work) and a Turbo 16/4 PCMCIA Token Ring card. The Oops is generated by a BUG() in ll_rw_blk.c. I'm quite sure this only happens when the network is active. I'll include the output of ksymoops and my kernel configuration. Since I'm not subscribed to the mailing list, I would appreciate a Cc: of any replies. The line in the syslog that precedes the Oops is Sep 14 20:13:21 hexane kernel: kernel BUG at ll_rw_blk.c:711! ksymoops ksymoops 0.7c on i686 2.4.0-test8. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.0-test8/ (default) -m /usr/src/linux/System.map (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
