The sound card on my laptop is not enabled.  Causes too many messages when I boot up and overwhelms the dmesg log file when I use the sound driver :
pcm0: <ESS Technology Maestro-2> port 0xf800-0xf8ff irq 5 at device 8.0 on pci0 (4p/1r/0vchannels duplex default)

I attempted to apply the patch, but I think the date on my in_pcb.c is incorrect.  What do I do to correct?:
# ls -al /usr/src/sys/netinet/in_pcb.c
-rw-r--r--  1 root  wheel  32712 Mar 28 06:29 /usr/src/sys/netinet/in_pcb.c
GandalfBSD# patch < ip_maxfragspersecond.patch
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|diff -u -r /usr/src/sys.old/netinet/in_pcb.c /usr/src/sys/netinet/in_pcb.c
|--- /usr/src/sys.old/netinet/in_pcb.c  Sun Apr 17 18:05:05 2005

File to patch: ^C#

Thanks,
