Re: How i can downgrade kernal to latest stable?
You need to provide more information. Which new kernel did you install? (give the terminal output of "uname -r")
When you install a newer kernel, it does not remove your older kernel version. You have to do that manually. Did you do that?

Re: How i can downgrade kernal to latest stable?
One small point to note here: the command uname -r only gives you the version number of the kernel package, not the actual kernel version. To get the actual kernel version, type:
linux-image-4.9.0-4 is the current kernel package in Stable, the actual kernel version is 4.9.51.
Code: Select all
apt-cache policy linux-image-4.9.0-4

Re: How i can downgrade kernal to latest stable?
If you want to run an older kernel version the select it from the "Advanced Options" GRUB submenu for the Debian entry — this will only appear if Debian is "controlling" the bootloader, you can boot from the symlink at /vmlinuz-old otherwise.
What exactly is the problem with the new kernel version?
Regressions in Debian stable are very rare.

Re: How i can downgrade kernal to latest stable?
I just wanted to see what kind of kernel upgrade he was talking about, Debian or some third-party one. "uname -a" will provide more information about the specific kernel version.
So it was a security upgrade of the standard Debian kernel that you mean. The older, vunerable version you wanted to revert to is no longer in the standard repositories. This is more an XY problem, too.

AFAIK, linux 4.9.0-4/4.9.51-1 is not a security update but was part of the recent 9.2 point release update (with ABI change -3 to -4).stevepusser wrote:So it was a security upgrade of the standard Debian kernel that you mean.

https://www.debian.org/News/2017/20171007
The latest (and earlier) linux security update was 4.9.0-3/4.9.30-2+deb9u5
https://www.debian.org/security/2017/dsa-3981
https://packages.debian.org/stretch/lin ... .0-3-amd64
AFAICS on the Debian site, it is still available (until the next linux security update).

Re: How i can downgrade kernal to latest stable?
But I don't see 4.9.0-3 available in the output of kernels from apt policy above, unless the OP truncated it without letting us know. And of course we don't see exactly what package they are checking, either.p.H wrote:AFAIK, linux 4.9.0-4/4.9.51-1 is not a security update but was part of the recent 9.2 point release update (with ABI change -3 to -4).stevepusser wrote:So it was a security upgrade of the standard Debian kernel that you mean.

Re: How i can downgrade kernal to latest stable?
before it drowns in noise, i'll repeat one more time:
op just thinks that the kernel is the problem. but since they're already using the standard stretch kernel, it's fair to assume that the real problem is something else.
op needs to tell us about the real problem.

Re: How i can downgrade kernal to latest stable?
This topic is about downgrading the kernel, not solving the real problem. If the OP wanted us to help solve the real problem, they would have described it instead of asking how to downgrade the kernel.
The OP has the latest stable kernel, which was released very recently and contains an ABI change. So, although it was a stable update, it is reasonable to consider that the problem, whatever it is, may be caused by a regression in the new kernel.
Note to the OP : unless you autoremoved unneeded packages or manually removed the old kernel after the upgrade, the old kernel is still installed and you can select it int the "Advanced options" submenu from the GRUB menu.

Try blacklisting the module that is named before the error message.
If that works and you can confirm that this problem does not exist when booted from /vmlinuz-old (ie, it is a regression) then please report this to Debian as a bug, I'm sure Mr. Hutchings will be very interested.
