The rx setup in init_ring() in drivers/net/natsemi.c in 2.4.6 is
miscompiled by several gcc-2.95 versions.

I could reproduce it with 2.95.1, and I received bug reports with 
gcc version 2.95.2 20000220 (Debian GNU/Linux)
gcc 2.95.3 19991030 from Mandrake 7.2

egcs-1.12 and rh gcc 2.96-85 are not affected.

Symptom: receive process hangs after 2 packets.

The patch also cleans up the suspend/resume synchronization and removes
2 superflous (& wrong) spin_unlock calls.
