Default EDAC Support

Dear all ,

as you know , EDAC is supported on main kernel of Debian , i have to say
that there are LOTS of issues with EDAC support in linux which made
Debian unusable on large range of Asus server and other bugy or stupid
hardware's , as i can say EDAC support seems very messy with kernel right
now .

while i was trying to install Debian on these servers , another red-hatish
pal of mine tried to install RHEL-5 on one of server , it was working like
o charm since those people solved this problem by not loading Edac modules
at all , This is the way!

i really suggest to remove Edac modules or atleast , prevent to
automatically get loaded somehow .

just blacklist them on your box if they do troubles,
/etc/modprobe.d

you don't even tell which version of linux-2.6 you tried,
nor what box that is (lspci) output.
so you report is currently just bla.
i see EDAC modules enabled in fedora.

this is lspci -v :
http://pastebin.ca/1018795

its debian testing . do not look at fedora since it was RHEL-5 ( Redhat enterprise 5 ) :
>[root@localhost 2.6.18-8.el5]# find . | grep -i edac
./kernel/drivers/edac
./kernel/drivers/edac/edac_mc.ko
./kernel/drivers/edac/k8_edac.ko
./kernel/drivers/edac/e752x_edac.ko
>[root@localhost 2.6.18-8.el5]#

of course this is a lot older than debian kernel , but still no problem by far


ps : by blacklist , i mean prevent them to load at all , not unloading ,
since there are more harm in this modules but something useful , i suggest
to disable them on normal and most important , on installer systems .

right way to do this is to disable both modules , let user choose , main
problem with debian kernel is lots of auto-loading .

hehe
the wiki page i gave you the link ask to test *latest* available,
so please see if you can reproduce errors in linux image 2.6.25
from unstable installs just fine in testing.

we don't disable functionality based on one "random" report,
i may still need more coffee, but i didn't see yet a dmesg
proof of misbehaving edac modules.
and if they do don't be shy to file upstream report in
bugzilla.kernel.org with dmesg and lspci output.
that would be the quickest way to get to a fix.

ps concerning irc you might want to google "screen irssi"
that way you can stay connected to a irc channel for
non interactive conversation and channel listening.

now , shall i report bug on kernel.org or just at debian kernel bugs ?

ps : again , i would really suggest to disable EDAC autoloading , add
edac_core to blacklist , look at huge amount of problem that edac causes ,
for sure , anyone who need this thing know how to modprobe , large range
of hardware's have issue with kernel EDAC support .

bugzilla.kernel.org is the place to report upstream.
