Can you check with 2.6.21? If that's OK, can you do a git bisect to figure out which change broke things? 2.6.21.6 is OK, so can I deduce that 2.6.21 is OK also? I am a newbie in kernel development, so sorry for the silly question. git bisect? OK, I will try to learn how to use git and git bisect.

You downloaded 2.6.21.6 from kernel.org, right? Just get 2.6.21 the same way instead and try that. > git bisect? OK, I will try to learn how to use git and git bisect.

Linus described how to do this here: http://groups.google.com/group/fa.linux.kernel/browse_thread/thread/af2a2d1151270a01/cdcaf2d55bb2f5e2?lnk=st&q=Linus+git-bisect+good&rnum=2&hl=en#cdcaf2d55bb2f5e2 Once you're you've got git going, git-bisect is a very simple, mechanical procedure. git is also a convenient way to get 2.6.21 if you feel like installing git before grabbing another tarball from kernel.org Jeff -- Work email - jdike at linux dot intel dot com - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Yes, I have downloaded 2.6.21, and it works OK. git bisect? OK, I will try to learn how to use git and git bisect. Wish I > could output something helpful. Linus described how to do this here: http://groups.google.com/group/fa.linux.kernel/browse_thread/thread/af2a2d1151270a01/cdcaf2d55bb2f5e2?lnk=st&q=Linus+git-bisect+good&rnum=2&hl=en#cdcaf2d55bb2f5e2 Once you're you've got git going, git-bisect is a very simple, mechanical procedure. I have followed the step described by Linus. git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 *$git bisect **good* v2.6.21 *$git bisect* bad v2.6.22 $git bisect The output is: Bisecting: 3420 revisions left to test after this [58936d8d944e27b75c99b1c59cfeea3f253b03cb] Char: cyclades, create cy_pci_probe but when I do the following steps: $cp arch/um/defconfig .config $make menuconfig ARCH=um and select to build ocfs2 in kernel. $make linux ARCH=um The build is broken. The error message is: SYMLINK arch/um/include/kern_constants.h SYMLINK arch/um/include/sysdep make[1]: `arch/um/sys-i386/user-offsets.s' is up to date.

I did the same step with the package I downloaded from kernel.org, and it works OK. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
