Hello!
I've upgraded my 6-STABLE (as of 20-Aug) to the fresh (24-Sep) RELENG_6.
The only modification of the kernel config file is the removal of the
IPFIREWALL_FORWARD_EXTENDED option. Upgrade went successfully, but after
booting into the multiuser mode I've found that /dev/smb0 became unavailable
(so I can't monitor my hardware with the healthd anymore). I've examined
kernel boot logs and found that the only difference is:
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 smb0 fails to attach to the smbus0 despite modules being loaded properly:
dmitry@homelynx$ kldstat|grep smb
21 3 0xc07b9000 29ac smbus.ko
23 1 0xc07c0000 4ff8 ichsmb.ko
45 1 0xc6974000 3000 smb.ko
I'm using all components of the SMBus attachment from modules:
dmitry@homelynx$ grep smb /boot/loader.conf
smbus_load="YES"
smb_load="YES"
ichsmb_load="YES"
I can provide any further information in order to help hunting the bug.
Sincerely, Dmitry
