[Bug 1854881] Re: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel
Hi Jeff, sorry - I tried to be as accurate as possible. In or out of fstab - I can only boot in the older kernel, 4.4.0-62 otherwise it freezes on boot. As per instructions on bug reporting, I ran lsb_release -rd, which printed 18.04.3 LTS on the first line, Release 18.04 on the second line. Seth on IRC told me to run a command which I did that then put all the debug info on this ticket. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854881 Title: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1854881] Re: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel
Note, I only ask because the kernel listed in some of the info is Ubuntu 4.4.0-62.83-generic 4.4.40 but you mention 18.04 and 18.04.3 and 4.4 and 4.15 and a whole mess of confusing info. So I just want to nail down exactly what kernel works, and what kernel fails. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854881 Title: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1854881] Re: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel
Just out of curiosity, you mention in comment #1 "p.s. I put the Iscsi target back in fstab, rebooted and selected the old kernel - it booted and mounted without any issue at all." Does this mean that at this point you can reboot and the system boots fine with the iscsi target in fstab? Or do you mean that it ONLY boots successfully using the old kernel, but if you boot the new one again, you're back to hanging? Which kernel successfully boots? (boot the system and do a `uname -a`) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854881 Title: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm sorry, I'm out of my depth when it comes to kernels. It is purely a test environment and I'm happy to give remote access and/or follow instructions, but, I'm really not sure how to do this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854881 Title: Boot hang after updating and setting up Iscsi with 4.15.0-72 generic kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
