well, my guess is that the compiler misscompiles your kernel.
stil _contrary_ to REPORTING_BUGS file you did not gave any info about
your system.
some usefull stuff you should email are (adjust it to your setup)
a)
cd /usr/src/linux
rm fs/buffer.o
make fs/buffer.o
email output of the make then find out what gcc was used (gcc,kgcc etc)
and email what gcc it was, ie
b)
gcc -v
then run following command
c)
gdb vmlinux
disassemble __remove_from_queues
in gdb run the above command and email output of all the 3 above,
then ppl on LKML might be able to help you better.
