Hi Mauricio, thanks for your support. I have attached the requested information to the bug. I had to pseudomize some of the logical volume names because they are considered sensitive, but I did so in a consistent way so the structure should still be clear. So that you don’t have to look through a

2020-03-18 Thread Sebastian Marsching
Public bug reported: After upgrading from kernel 4.15.0-88 to 4.15.0-91 one of our systems does not boot any longer. It always crashes during boot with a kernel panic. I suspect that this crash might be related to Bcache because this is the only one of our systems where we use Bcache and the kern

Hi Mauricio, there is the problem that this tarball contains an awful lot of sensitive data, some of that personal data that is protected under the GDPR. Maybe you could tell me which specific parts / sections you are interested in, so that I can anonymize and upload them. Thanks, Sebastian --

Hi Mauricio, according to my Bash history, I used the following two commands to create the Bcache device: make-bcache -B -b 524288 -w 524288 -o 8192 /dev/vg0/vg2-backend make-bcache -C -b 4194304 -w 4096 -o 8192 /dev/vg1/vg2-cache I think the reason why I used this block size was that the MD RAI

I think that unlike the bug title and description suggest, this bug is not limited to IPv6. I am having the same problem with FreeRADIUS when RADIUS packets are received over IPv4. This problem is fixed by the Kernel from trusty-proposed, too. Actually, this problem looks a lot like a regression t
