Hello!
I'm in a process of upgrading our FreeBSD 5.3 servers to 5.4. Two done,
one to go. I noticed that the Giant lock is no longer mentioned in dmesg
during boot. With FreeBSD 5.3, several devices (for example: ips, ahc,
atkbd) had a note similar to this in dmesg:
ips0: <IBM ServeRAID Adapter> port 0x2000-0x20ff mem
0xfeb00000-0xfebfffff irq 9 at device 1.0 on pci0
ips0: [GIANT-LOCKED]
With FreeBSD 5.4, the [GIANT-LOCKED] message no longer appears.
Does that mean that Giant lock has been removed from all those drivers,
or is the message simply not printed?
