Since the beginning of the month, automatic reboot after kernel change takes ... 3 hours.

It is a Lenovo Thinksystem server in a datacenter.

journalctl -b -1 ends with:

juil. 23 03:02:25 host systemd-shutdown[1]: Sending SIGTERM to remaining processes...
juil. 23 03:02:25 host systemd-journald[658]: Journal stopped

and journalctl -b starts with:

juil. 23 06:16:26 host kernel: microcode: microcode updated early to revision 0x2006906, date = 2020-04-24
juil. 23 06:16:26 host kernel: Linux version 4.15.0-112-generic (buildd@lcy01-amd64-027) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #113-Ubuntu SMP Thu Jul 9 23:41:39 UTC 2020 (U
juil. 23 06:16:26 host kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-112-generic root=UUID=7b9c74b1-d80e-457e-957a-32be0fca891e ro

I have a GRUB_TIMEOUT=0 so I have no idea of what could be the issue.

Edit:

One weird thing is that lshw used to show the server model:

product: ThinkSystem SR590 -[7X99CTO1WW]- (7X99CTO1WW)
vendor: Lenovo
version: 04

And now:

Edit 2:

It seems to be stuck on that screen for hours:

  • The hardware specs of the server may be interesting. Any external USB disk drives or the like connected to the server?

  • Watch the console during the reboot to see what the system is doing.

It was not possible to fix it remotely. It was not possible to enter setup or boot menu without waiting hours. It happened by itself, not power outage or anything. Weird for a server class product ...

I fixed it by resetting the CMOS using the motherboard jumper, the manual explains how to do it.

Now the system model, serial and so on are available to the OS and the onecli tools works as it should.
