problem regarding KGDB on FC3

[umesh chandak <chandak_umesh@yahoo.com>]

hi ,
         I have applied a KGDB patch on FC3 for kernel

2.6.10 .
         My connection is successful with command 
target remote /dev/ttyS0

After pressing C for continuing i got some messages on
console ,after that my target m/c did not start 
error messages are like this .
--------------------------------------------

(gdb) target remote /dev/ttyS0
Remote debugging using /dev/ttyS0
breakpoint () at kernel/kgdb.c:1446
1446            atomic_set(&kgdb_setting_breakpoint,
0);
(gdb) c
Continuing.

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically. 
If this
** causes a device to stop working, it is probably
because the
** driver failed to call pci_enable_device().  As a
temporary
** workaround, the "pci=routeirq" argument restores
the old
** behavior.  If this argument makes the device work
again,
** please email the output of "lspci" to
bjorn.helgaas@hp.com
** so I can fix the driver.
