------- Comment #19 from [EMAIL PROTECTED] 2008-12-05 18:20 -------
Dear ykzhao,
I have confirmed that this problem exists in 2.6.25.19, 2.6.26.7
and 2.6.27.{1,2,4}.
I tried to blacklist all USB related modules on 2.6.27.x and have
confirmed that this problem exists when USB modules are blacklisted too.
(I have already mentioned the above on LKML.)
I would like to clarify one thing. When I boot using "noapic",
the version of the kernel does not matter; I always get a "nobody
cared" message during boot.
However, when I boot with*out* "noapic", that is, normally, then
I only get "nobody cared" messages after the computer has been on
for a while - and only for certain kernel versions. Please read on.
=== Important update ===
Furthermore, I have found out that this problem was introduced by
a change between 2.6.24 and 2.6.25. I have found this out by using
2.6.24 for quite some time and noticing that I did not get any
"nobody cared" messages, even though I had reduced the check number
for the spurious IRQ counter to "99".
I have partially bisected the commits between 2.6.24 and 2.6.25 and
have made some progress. I have waited 48 to 70 hours using the kernel
built by each iteration of the bisection. If I got a "nobody cared"
message, I used "git bisect bad". Otherwise, "git bisect good".
Unfortunately, I don't have the time these days to continue bisecting.
(I am kind of busy.) I will have the time about one-two weeks later.
I am going to attach the current output of "git bisect log" in a moment.
Please note that the bisection isn't finished yet. As I said, I will be
able to continue bisecting in a few weeks.
Regards,
M. Vefa Bicakci
