You need to install openssl-devel, so it'll fix this issue :)

git bisect would be a choice.
Seems your issue is around i915, that is related to intel graphics,
isolate commits in this area would be another way

IMO, I believe if you module is using/hanging all processors it's
impossible to kernel use any to print stuffs. What about try Sysrq [1]
? I used it once in a power system plus xmon, but I'll be honest not
sure how it works on x86.

For memory leaks kernel has a clever mechanism to verify it that you
can enable in .config for use [1].
You can also uses Sparse in kernel for static analyze purpose.
There are others out there such as coverity scan, coccinelle, etc.

I often delete files related to these kernels in /boot/, then
grub2-mkconfig -o /boot/grub/grub.cf , but I'm quite sure lib/modules
will still remain

it means you don't want to redefine a .h file

Yep, I can try. Do you know when this issue start ?

With this .config you sent kernel does not boot.

I could boot it using qemu. So what's the point?

Hi there,
I'm facing with an issue that from a module the user sends a scatterlist
which has sizes not power of two and because that I can not handle it
properly in my module in other side.
An example is:
- scatterlist entries size 3 and data size 4096.
- in other side module needs to build blocks
git grep is your friend. :)

Sometimes they take a long time to answer, maybe they are stuck again,

Did you type make modules ? It's sounding as module issue.

I sent the first lines from dmesg, it shows the info of system boot.

As they say, kernel code is the better and updated
source/documentation. There is no an updated book.

better.

Sorry, silly question, but did you try as root? kexec load tries to put the
knew kernel on memory and after that tries a syscall to kexec_load to
finish with a kexec_reboot, since it handles with mem and syscalls maybe
just as a root you will run it properly
Also have that ke...@lists.infradead.o
Hi,
I'm working in a project and there I need use kexec code to do somethings.
I read a lot of the kexec-tools code (user-land) and kexec-sys call
(k-land) and I'd like to be sure about some arguments there.
In kexec we have that kexec_image and into it that nr_segments and the
segments itself. I
I don't know if it can help you, but let's try. [1]
What I understand about that is. The compressed kernel is in fact a bzImage
or some zImage kernel, and it is a file. As the link says in that
compressed file we have this header that makes some early configurations.
The kernel is uncompressed into
Hi,
I'm trying to do some maps in early kernel boot and grab some error when I
try unmap a pointer/memory that mapped it before. Basically it shows me the

I'm maping it like this: table = early_ioremap(offset_address, table_size);
and unmap it : early_iounmap(table
