Mine:
openat(AT_FDCWD, "/dev/ipmi0", O_RDWR) = 3 <0.52
Yours:
openat(AT_FDCWD, "/dev/ipmi0", O_RDWR) = -1 EINVAL (Invalid argument) <0.53>
So we are back at the kernel backend of this - on your particular
hardware/firmware - not behaving correctly. This isn't one of the later

Sorry, wasn't sure how to upload it in a text file, so here's the output
of the stack trace.

Yeah I did try that (saw it somewhere among the web) but it pretty much
gives nothing, because of the main error.
root@x:~# strace -rT -ff -o ipmitool.strace ipmitool lan print

Hmm, so your system indeed has /dev/ipmi0 then (also you had that implicitly in
comment #4 already) - thanks.
But that means we are back at the beginning with the but triggering for you but
being non reproducible in other places :-/

Title:

I've given the mods loaded in my initial comment. The output of ls -laF
is the following:
root@x:~# ls -laF /dev/ipmi0 /dev/ipmi/0 /dev/ipmidev/0
ls: cannot access '/dev/ipmi/0': No such file or directory

Not sure why it's marked as invalid. This appears on Ubuntu 18.04 with
the same error.

I'm marking this report as Invalid then. Thanks for the follow-up!

Title:
I confirm ,run all command with root. After the machine restarts, all ipmitool
are back to normal.I don't know why.
I try on other machines , and the problem cannot be reproduced.
Thank you very much.

Thanks for your report. Let's rule out the simplest hypothesis: are you
running the command as root? I can reproduce the error you observe
running ipmitool as an unprivileged user:
$ ls -l /dev/ipmi0
crw--- 1 root root 239, 0 May 30 13:39 /dev/ipmi0
$ ipmitool lan print
