I'm using Debian unstable/sid/lenny with homemade kernel 2.6.23.12
patched with tuxonice-3.0-rc3-for-2.6.23.9 and compiled with
gcc version 4.2.3 20071123 (prerelease) (Debian 4.2.2-4).
My root file system is xfs which does not have "noatime" option.
I was "tar xf"ing a big tar ball when this happen and ultimately leads to a
hang up. I am trying to reproduce it again in a similar setting virutal
machine,but till now it does not happen again.
I will provide further details if it appears again.
The objdump for touch_atime of my vmlinux is as follows:

The D flag here indicates that the kernel has already oopsed before.
The first oops will be probably more important (this second one is
likely just an fallout). Are you able to get the first oops?

Hi,
Sorry for the late reply, I was off for a few days.
Saddly, I never reproduced the bug.
I moved my main machine to an older kernel and let a virtual machine track down the bug,
but it never appeared again --- possibly because of the simpler hardwares.
And just as you say, I also think it should not be that place which origins the bug,
because no inner called functions even touched the stack.
I think "mov (%esp),%ebx" can only be bad on a corrupted stack.
I will come up with more detailed info if the same problem appears
and I catch the very first bug.
Thanks a lot for your responding.
