Subject: i2c-piix4 oops
X-Spam-Status: No, hits=0.0 required=5.0 tests= version=2.20

Hello,
Sorry if I'm wrong writing you.
I have Fujitsu Lifebook based on I440MX, then I'm trying to use i2c-piix4 on
kernel 2.6.4, it loads successfully, but then I'm testing it with for example
i2cdetect from lm_sensors package it goes in oops like:
Mar 25 08:39:44 lifebook kernel: Unable to handle kernel NULL pointer
dereference at virtual address 00000000
Mar 25 08:39:44 lifebook kernel: printing eip:

Mar 25 08:39:44 lifebook kernel: esi: 00000705 edi: 00000705 ebp: c78e4470
esp: c5e93ef0
Afterwords if I try to rescan buss it writes:
Error: Could not get the adapter functionality maxtrix: Inappropriate ioctl
for device
I've tried to load with fix_hstcfg=1, it doesn't help me.
I tested this on kernel 2.4.22 and all goes ok (no oops, and buss function
properly)
I have more messages in attachment.
PS. If I'm wrong, or shouldn't write to you and should write to somebody
other please say me.
Thank you
