lm78 hwmon stopped working after upgrading from Sarge (kernel-image-2.6.8-3-686
version 2.6.8-16sarge6) to Etch (linux-image-2.6.18-3-686 version 2.6.18-7).
The system is an Asus P2L97S, having a LM78-J on ISA port 0x290. This used to
show up as the directory /sys/bus/i2c/drivers/lm78/0-0290/. After upgrading,
this directory has disappeared:
canardo:/home/bjorn# lsmod|grep lm78
lm78 15988 0
i2c_isa 5152 1 lm78
hwmon_vid 2784 1 lm78
i2c_core 19680 6

sensors-detect still finds the chip:
...
Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM78-J' at 0x290... Success!
(confidence 6, driver `lm78')
Probing for `National Semiconductor LM79' at 0x290... No
...
Driver `lm78' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `National Semiconductor LM78-J' (confidence: 6)
...
But sensors can't read anything (as expected since the sysfs entries are
missing):
canardo:/home/bjorn# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
Let me know if you need more information about the system.
