Run the debugger on the binary, not the debug symbols:

Yeah.  I think the idea is to delete the old base-system kgdb when
you install the port.

It seems the devel/gdb80 port installs a kgdb symlink
to kgdb80.  So, I'm not getting the correct kgdb due to 
my path.  Ugh.

Hello.

 My notebook was a little bit panic this night. After rebooting I found 
  this message in my system log:
 
  panic: softdep_deallocate_dependencies: dangling deps

I've been seeing this panic on NetFinity 6000R since end of September.
-CURRENT is installed on a RAID partition, and the partition is controlled
by ips driver, so it's possible that the root of my problem is completely
different from yours, but anyway...

To reproduce it, enable dump device and create many files in a directory:

# mkdir foo; i=0; while :; do echo -n $i  foo/$i; i=$(($i + 1)); done

and go to bed and you'll get a kernel dump in the crash dump directory
in the next morning. At first I thought that the hard disk is damanged,
but the following dd command doesn't panic the machine, just fills up
the partition many times.
# while :; do dd if=/dev/zero of=BIG bs=1048576; done

With -CURRENT built from source as of D2003.10.21.00.00.00, I'm still
able to reproduce this panic, together with new one:
panic: handle_written_inodeblock: live inodedep

Backtraces are available on request.

It should be rev 1.397 of vfs_bio.c, I updated the sources just before the

  When are your srouces from?  Specifically, what version of vfs_bio.c do
  you have?
 

 It should be rev 1.397 of vfs_bio.c, I updated the sources just before the

Jeff
