Hi All:
anybody who met such error of Android application? the logcat will be
something like below:

Can you please point to some code in Linux Kernel that does the job?
In kernel/exit.c, look at do_exit(). It cleans up a process after it's
terminated (for whatever reason).
It does a lot of cleanup, but through exit_files() - put_files_struct()
- close_files() it ends up iterating

Hello all,
I'm building a linux system for a new architecture,
and I want to use initramfs support to build a filesystem.
I have seen that there are several ways to do that with initramfs.
Either the kernel will build the cpio archive for me, or I can provide an
external one with the
hi,
I had build kernel 2.6.39 from the Debian Squeeze backports, with buildin
initrd for booting sparcs over OpenBoot. The kernel works with a Sunfire a
v245. Now I try the same with the T2000 (Enterprise), but the kernel doesn't do
anything with NFS, after the last DHCP resquest.

Hi 卜弋天,

i'm fairly sure i know the answer to this, but i figured i'd run it
by others just to make sure i'm not missing anything subtle.

Hi,
I was hoping somebody could enlighten me on how serialization of access
to data in struct net_device and associated netdev_priv() data works in
the callback functions registered in net_device_ops. For example, I am
looking at drivers/net/e1000/e1000_main.c in my 2.6.32 based kernel
tree. My

Hm, sounds like a bug during suspend. Perhaps you can do strace
pm-suspend. And/or enable CONFIG_DETECT_SOFTLOCKUP. And hopefully you
can pinpoint the related syscall or kernel instruction that leads to
the bug
It's not that easy. The problem occurs only when I'm going to suspend
