[1.] One line summary of the problem:
Kernel BUG() in 2.3.99-pre7-1
[2.] Full description of the problem/report:
I get a
"kernel BUG at /usr/src/linux/include/linux/mount.h:41!"
when using "fuser" on 2.3.99-pre7-1. The system is still stable.
[3.] Keywords (i.e., modules, networking, kernel):
kernel, oops, fuser
[4.] Kernel version (from /proc/version):
Linux version 2.3.99-pre7 (tek@tek01) (gcc version egcs-2.91.66
19990314/Linux (egcs-1.1.2 release)) #17 Sat Apr 29 12:24:28 CEST 2000
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
ksymoops 2.3.3 on i586 2.3.99-pre7. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.99-pre7/ (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.
