Yinghai,

Please advise me on how you would like me to handle 2.6.27 kernels.
If I use your patch on 2.6.27-rc3, the message scroll off the 80x25
screen before I can see them... and then the kernel hangs. I can run
the kernel with "hpet=disable", but I'm not sure you want that. If
you _do_ want that, just let me know.

As an alternative, I can alter your patch to use a log level of
something lower, like KERN_WARNING. Then I could see the messages
from your patch if I set a "loglevel=4" boot parameter, even on a
kernel that hangs. The normal messages should disappear, only
leaving the messages from your patch.

In the meantime, here is what I _did_ do to test your patch:

==================================
$ git checkout -f v2.6.27-rc3
HEAD is now at 30a2f3c... Linux 2.6.27-rc3

$ git apply --verbose --check ../yh_insert_resource_debug.patch
Checking patch kernel/resource.c...

$ git apply --verbose ../yh_insert_resource_debug.patch
Checking patch kernel/resource.c...
Applied patch kernel/resource.c cleanly.

$ git status
# Not currently on any branch.
# Changed but not updated:
# (use "git add <file>..." to update what will be committed)
#
# modified: kernel/resource.c
#
no changes added to commit (use "git add" and/or "git commit -a")
==================================

This kernel boots and hangs, and I cannot see your patch messages. But
I am sure they are there. (See below.)

To see your patch messages without altering the patch, I checked out
an older revision that will boot. Also, I just realized why I never get
the earliest boot log messages from 'dmesg': the standard value of
CONFIG_LOG_BUF_SHIFT is 15 (32 KB), which is too small to capture all
of my early boot messages.

In view of these things, I checked out the last kernel that will run for
me without hanging,

$ git checkout -f 700efc1b

and set CONFIG_LOG_BUF_SHIFT=18. Your patch messages show up nicely this
way:

==================================

Just let me know how you would like me to handle a crashing kernel, if
this output is not sufficient. I don't think all of your patch
messages would fit on one screen, though, even if I made the
KERN_WARNING change that would allow me to see them.

Thanks,
