>Description:
I enable the software watchdog, then suspend the machine and capture
output on serial console:
Lock GEOM topology not exclusively locked @ ../../.
./geom/geom_subr.c:261
acd0: WARNING - removed from configuration
sio4: detached
The machine is fully suspended at this point. Now I resume the machine:
pci_cfgintr: 0:29 INTA BIOS irq 9
pci_cfgintr: 0:29 INTB BIOS irq 11
pci_cfgintr: 0:29 INTC BIOS irq 9
pci_cfgintr: 0:31 INTB BIOS irq 5
pci_cfgintr: 0:31 INTB BIOS irq 5
pci_cfgintr: 0:31 INTB BIOS irq 5
pci_cfgintr: 1:0 INTA BIOS irq 9
pci_cfgintr: 2:0 INTA BIOS irq 9
pci_cfgintr: 2:0 INTB BIOS irq 5
pci_cfgintr: 2:0 INTC BIOS irq 9
pci_cfgintr: 2:2 INTA BIOS irq 9
pci_cfgintr: 2:8 INTA BIOS irq 10
ata0: resetting devices ..
Normally the machine would lock at this point with the hard disk light on.
The only way to fix it is to power down and back on. However, since I have
enabled the software watchdog, I simply wait a few seconds and I receive
this:
interrupt total
irq0: clk 18254
irq1: atkbd0 9

I hope the above information is helpful. I'm not a kernel programmer. I AM
familiar with C, but I'm not very good with debuggers. Please let me know
if you need additional info. Thanks!
>How-To-Repeat:
Step 1: Fn + F4 to suspend machine
Step 2: Fn to resume machine
>Fix:
unknown.
