Bug#719623: linux-image-3.10-3-amd64: still present in 3.10-3-amd64
The joyful news I received today is that the patch has been committed upstream to the 3.10 stable tree: http://git.kernel.org/cgit/linux/kernel/git/stable/stable-queue.git/commit/?id=47b04e91606a459a5c60abc6a5d03bcc6bd6d801 So I trust that it will make it into Debian soon.

Bug#723180: Double fault when single-stepping compat task with PREEMPT_RT
On Tue, 2013-09-24 at 13:43 -0700, Brian Silverman wrote:
[...]
I got down to a really simple program that reproduces this bug:
#include sys/syscall.h
#include unistd.h
int main() {
// I've tried SYS_getpid, SYS_write, and SYS_read here too.
syscall(SYS_gettid);
}
Any syscall I put in there seems to give the same results. In order
for it to trigger the bug, you have to compile it with `gcc -m32
whatever.c` (I'm testing with the standard Wheezy gcc (4:4.7.2-1) and
gdb (7.4.1+dfsg-0.1)). I would imagine that something in gcc and/or
gdb is contributing to this too.
I also minimized the gdb commands down to:
break main
run
record
I assume this enables single-stepping.
continue
[...]
I can reproduce this in VMs running the latest Debian RT kernel versions
(based on 3.2.51-rt72, and on 3.10.11 with the 3.10.10-rt7 patch).
As Brian says, x86_64 userland on x86_64 kernel works, and similarly for
i386 on i386. So it is specifically the 'compat' case that's broken.
Here's what I got:

Bug#692957: Info received (Bug#692957: linux-image-3.2.0-4-amd64: NFS server causes high load on 3.2 kernel)
Unforunately I could not follow up on the issue anymore because I had to get my systems back into a running state. If nobody else can reproduce it on Debian, then it is possible that the issue was indeed related to Ubuntu only or the specific kernel version used there. So this bug can probably be closed.

This change let the strange behaviour to gone. Summary: The issue occurs only with a new kernel e.g. 3.9-1 and an IDE disk connected via sata2ide only. The old kernel 3.2.0-4 doesn't show this behaviour. A new kernel and a direct attached SATA disk works fine again.

Removing some kernel-related virtual packages
I'd like to stop the binary packages built from linux providing the following virtual packages: * linux-image As explained in #724569, any relations on a virtual package prevent auto-removal of all providing packages, so in this case linux-image-* packages must be manually removed to avoid filling up /boot. And it is the job of the installer to make sure systems get a kernel installed; there is no sense in random packages also recommending/suggesting it! * linux-headers Same problem with auto-removal. The linux-headers-flavour metapackages built by linux-latest also provide this virtual package, and the recommends/suggests should really refer to these. * linux-source Same problem with auto-removal. This is also the name of a real metapackage built by linux-latest, which again is what the recommends/suggests should really refer to. * linux-kernel-headers This used to be the name a real package, which was replaced between etch and lenny by linux-libc-dev. There is one remaining reverse-dependency (libkxl0-dev, #724639) which would need to be fixed first. Any objections?

Hi,
Here's a patch to lsinitramfs to deal with initramfs images that start
with the microcode archive and then a real archive afterwards.
