[2.5.67] buffer layer error at fs/buffer.c:127; problems with via686a sensor

["Tomasz Torcz, BG" <zdzichu@irc.pl>]

Hi,

infos about my system is here: http://fordon.pl.eu.org/~zdzichu/my_setup/
(lspci, output of some files from /proc, dmesg and .config).

I've got some unexplained Call Traces in dmesg:

buffer layer error at fs/buffer.c:127

What is that?

Also, I had problem compiling via686a sensors into the kernel.
First, it complained about missing i2c_detect(); I've
replaced it by i2c_probe(); kernel has built and booted.
Only sysfs directory of sensor is empty :(
It works with 2.4.x lm_sensors (via /proc of course).
