If a computer has a different operating system other than FreeBSD , such a crash is occurring during the first boot . I think the reason is that parts that are NOT able to use the newly stored microcodes . In a new boot , the above mentioned parts are becoming able to use the stored microcodes during the first boot .

13.0-RC5 crash/reboot on cold-start, how do I get a textdump ?
Hi! I have a new laptop (Lenovo P14s), installed freebsd 13.0-RC5 on it with ZFS, geli encryption. If I cold-start the laptop, the first boot will crash before going multi-user and reboot, and the next boot will be fine. I activated /var/log/kern for kern.*, but the crash happens so early that nothing is logged. How can I get a textdump of that crash ? Would boot_ddb="YES" in /boot/loader.conf help ? -- p...@opsec.eu+49 171 3101372Now what ? ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. If you add or take away from the above definition, then there is your misunderstanding. IMHO many refer to Linux as an Operating System. When in fact it is a Kernel. Which is also what you describe above. OTOH, UNIX as an OS has a defined set of commands available, as well as servers to facilitate running a fully installed server. Which is what I believe he was referring to. At this point I think this thread is becoming tiresome. ;-) --Chris Best Regards, Vic Thacker On Wed, Apr 7, 2021, at 21:17, tech-lists wrote: Hi, I'm a bit late to the discussion On Mon, Apr 05, 2021 at 07:44:59AM -0700, Cy Schubert wrote: >I think this is an excellent start.

Very firmly against this, and this sort of thing, for the following reasons: 1. I want an OS, not a kernel. If I just want a kernel, then why not go with linux? FreeBSD is meant to be, I think, (generally), a server OS. So, would you agree that it needs the ability to have server protocols easily configured, with a minimum of fuss, without packages? 2. a lot of infrastructure depends on ftpd. it's easy to configure securely ftpd in base. 3. there are some networks, like internal ones, where encryption is not a requirement, or appropriate. 4. there are some places where encryption is in fact illegal. >Personally, I'd suggest we remove the ftpd server *AND* ftp client and rely >on ports.
