Adding finsio0 hang kernel



Hi i386 list !

I’m using an old motheboard (ATOM N270, with 945GSE and ICH7 bridge) which has a Fintek F71882FG (or similar) for voltage monitoring.

But adding "finsio0 at isa* port 0x4e" in the kernel make it unbootable. If I change the isa address (0x2e by example, or 0xa00 as found by lm-sensors), I’m able to boot but the chip is not detected. So, I guess 0x4e is the correct one.

It locks just after probing coretemp and second CPU:

[     1.0178368] isa0 at ichlpcib0
[     1.0178368] pckbc0 at isa0 port 0x60-0x64
[     1.0178368] acpicpu0 at cpu0: ACPI CPU
[     1.0178368] coretemp0 at cpu0: thermal sensor, 1 C resolution, Tjmax=90
[     1.0178368] acpicpu1 at cpu1: ACPI CPU
(locked here, I can’t go back in console to see if finsio was detected)


When finsio is not in the kernel, the dmesg is a bit different (ACPI P-state and C-state are printed before coretemp and cpu1):

[     1.017352] isa0 at ichlpcib0
[     1.017352] pckbc0 at isa0 port 0x60-0x64

[     1.017352] acpicpu1 at cpu1: ACPI CPU

Any idea ?

Thank for your help !


Best,
