For a time, listing them in /etc/src.conf would get them rebuilt automatically as a sort of epilogue to building a kernel, but then something changed quite a while back, and I had to comment that line out and return to doing them manually. Often they still work without being rebuilt, and I got careless this time. Sigh. > > Recompile any kmods from ports and you should be ok.

Ah. I suppose I will see that while catching up on my latest email backlog caused by six days or so with no working system.

I've cc'ed the list this time. FWIW, once of the things I have been wishing for in trying new revisions of 11-STABLE is a fix for the failure of the kernel to honor the vm.max_wired sysctl variable. The crash that gave me an opportunity to try the broken revision was another case of the kernel having pagefixed so much real memory that it was not only causing paging/swapping when it should have, but I think the kernel itself couldn't get page frames it needed fast enough in some situation. I don't know whether this bug has been found and fixed yet, though, so I have temporarily returned to setting vm.kmem_size_max, which does seem to be honored. Anyway, thanks for bailing me out yesterday. The system is now somewhat usable while I satisfy my curiousity and should be fully usable upon reversion, which will probably happen tomorrow (Monday) night. Scott Bennett, Comm.

I am still exploring what is new/changed in this revision (besides a broken zfsloader), and I do have mprime back to work for the time being, so reverting can wait another day. I have reverted a few times in the past, but was always able to start that from the boot menu. This time really threw me until I received a reply to my plea for help telling me how to use the previous loader to get to the boot menu. I had already successfully run the r347183 kernel in single-user mode, so I figured I could do so again. What broke the zfsloader was the installworld step. After reverting to r345498 I will try bringing my source tree up to date, which would be quite a bit later than this broken r347183, and then run a fresh buildworld and buildkernel anyway. If all that fails, then I'll just go back to r345498 again and sit it out until 11.3-RELEASE happens before trying again. Scott Bennett, Comm.

Out of curiosity, you mentioned in your previous email you created a new boot environment for this upgrade… since additional issues remain beyond the loader, have you considered rolling back to the known-good BE and attempting the entire process again (with another, separate BE) in a week or so? Especially since that would hopefully allow you to continue your other work without any additional issues or oddities to sort through in the meantime? -- Matt ___ 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"

So far I've received one reply, which was not copied to this list, yet the person responding suggested something to try and also adked that I post the result to the list. I would have done both anyway, but the respondent may have desired anonymity on the list, so I am not quoting the message I received. The suggestion was to wait about a second after entering the GELI passphrase and then hit the space bar on my keyboard. At the resulting prompt, I should enter the path given in the prompt, but with ".old" appended. I did that, and YES!!! It worked and proceeded until I had a boot menu. I opted for single-user mode and then responded to further requests for GELI passphrases until eventually I had a root shell. Being unable to reach the boot menu was a problem hadn't previously even crossed my mind. I certainly hope that doing updates from source in the future will not cause this same booby trap again. At that point I renamed /boot/zfsloader to /boot/zfsloader.bad.r347183 and /boot/zfsloader.old to /boot/zfsloader. I also added a hard link to the latter as /boot/zfsloader.good.r345498. All is still not well, however. In multi-user mode, startx turns the screen black and switches its power setting to standby. After that it remains unresponsive until I log in via a different vt and send SIGHUP to xorg. After a rather lengthy delay (30-60 seconds, at a guess) it returns to the login session on the console vt. I have now commented out the "kld_list="/boot/modules/radeonkms.ko" line in /etc/rc.conf.local in hopes that the next boot will get the scfb driver to take it instead of the radeonkms driver from graphics/drm-next-kmod. If someone knows, is this a case where rebuilding and reinstalling graphics/drm-next-kmod? If so, then I will do that, but I see that the Makefile still appears to use the same distribution file. Many, many thanks to the person who responded with the solution to get past the loader crash!! My system is now getting work done again, and the rest of the new problems can be dealt with on a running system. Scott Bennett, Comm.

11-STABLE system unbootable after update
I have been running 11.2-STABLE for a while at r345498. Last weekend it crashed, so I took the opportunity to install the most recent build I had lying around, r347182. I created a new boot environment and installed the r347182 kernel into it, shut the system down, and rebooted. The new kernel came up and appeared to be working okay, so I continued with the mergemaster -p -F, make installworld, and mergemaster -F, then shut it down again, and rebooted. It asked for the GELI key for the boot pool, which I then entered. The spinning slash cursor appeared and may have changed for one frame or so, and then I got a message beginning with "BTX" and followed by several lines of hexadecimal, and then it stopped. I tried it again just to be sure, and the result was exactly the same. Does anyone know whether the PMBR boot block or the loader in the freebsd-boot partition changed between r345498 and r347182? I found no warning in /usr/src/UPDATING about installworld potentially leaving a wasted system, so I don't have a clear idea of what went wrong, much less whether I missed some instruction somewhere about source updates. If anyone can lend me a clue here, I would greatlyappreciate it. I only had one working machine, and now it is only working in a "rescue" mode by booting from a DVD. (Probably needless to say, but I will burn new DVDs with up-to-date stuff as soon as my system is working the way it is supposed to again.) This motherboard is nearly 11 years old and does not boot from USB (in spite of the BIOS menus say), so at the moment I am logged into SDF by running a long out-of-date TrueOS installer DVD, which happens to be a pain to get to boot all the way, but I've figured how to make it do it rather than get stuck with a logo on the screen that never goes away. Unfortunately, it includes no software to burn a CD or DVD, so I cannot make a new bootable disk for the time being. I will check email much later today or this evening.
