  • Sun Ultra 45: Kernel Panic (corrupted stack end detected inside schedul

    From jake@pawlicker.com" @21:1/5 to All on Thu Oct 13 05:50:01 2022
    On my Sun Ultra 45 with two CPUs, Debian does not boot a finished installation using Kernel 5.19. On the 5.16 kernel included on the CD the OS boots just fine if this is selected using GRUB. This also seems to be intermittent, as first booting into 5.19
    was stable after trying to use quiet to get an error log after a 5.16 boot, but then rebooting afterwards gave me a more verbose error:

    I've also been able to confirm that this happens with Kernel 5.16 or at least similar bugs do such as Unable to handle kernel NULL pointer dereference, programs such as postgresql break dramatically, and another time SSH panicked the system with a kernel
    unaligned access. This happened during apt-get:

    There seems to be a problem with UltraSPARC T1s and I strongly believe
    this or another problem also affects UltraSPARC III(i)s. I have tested a variety of processors here:

    (Since I didn't hit reply all on the previous one, whoops I'm not so good at mailing lists)

    Thanks for the advice. The 5.16 CD is stable enough to pass the installation (aside from a video text bug), however in rebooting it blows up. I was able to console install it using the same trick as with the U10 (setting the output and input devices to
    TTYA). I'm going to post what I did here so anyone else with an UltraSPARC III/T1 based machine can get "something" going.

    I initially tried the 4.19 CD however after grabbing the new gpg key and doing an upgrade once the OS was installed it blew up a few minutes in. Namely the upgrade failed really early on and I was unable to sudo, and if I logged out I was unable to login
    as well. It didn't even try to let me enter in a password, it simply told me that it was incorrect.

    So what I did was I used the 5.16 CD, then when I was asked the tasksel question I used Ctrl-A and 2 to move to the shell, chrooted /target, and used busybox wget on the kernel you linked and installed it. This gave me a working system with the 4.19
    kernel. For some reason or another though networking did not want to work on 4.19, so I mounted the CD, and installed the deb and udebs from there (and the kernel image from https://snapshot.debian.org/archive/debian-ports/20190622T024525Z/pool-sparc64/
    main/l/linux/), and networking finally worked. I'd install that too or the other udebs for the one you linked instead of just using the kernel.

    Now it's rock solid and I can do my weird SPARC experiments. Thanks so much.

    I'm also experiencing this problem with the
    debian-12.0.0-sparc64-NETINST-1.iso from 2023-05-16 on a SPARC T4-2
    (sun4v). Logs are as below; a Debian 11 image from last year works fine (unfortunately with an unknown burn date).
