This commit has broken SMBus attachment at least on ICH4; boot messages
difference (diff -u old new) gives only 1 line missing:
ichsmb0: <Intel 82801DC (ICH4) SMBus controller> port 0xe000-0xe01f irq 17 at
device 31.3 on pci0
ichsmb0: [GIANT-LOCKED]
smbus0: <System Management Bus> on ichsmb0
-smb0: <SMBus generic I/O> on smbus0
So with the new SMBus modules smb0 no longer attaches to the smbus0 despite
having all 3 modules loaded as before:
dmitry@homelynx$ kldstat|grep smb
21 3 0xc07b9000 29ac smbus.ko
23 1 0xc07c0000 4ff8 ichsmb.ko
45 1 0xc6974000 3000 smb.ko
After reverting the contents of /sys/dev/{ichsmb,smbus} to the pre-commit
state (date=2006.09.22.19.19.00) and recompiling the modules (smbus, ichsmb,
smb) I've got working SMBus subsystem again. Please look into this problem.
Sincerely, Dmitry
