Cant run DietPi Trixi (crashes when bootup), so no access to logs, only some error on screen (should’ve taken a picture…) It happened to my with every release of trixie. So its not specific to 10.1.
Can run Bookworm, but can’t update, here is the pic:

How can I make it update?
Why trixie crashes? Should I provide pic? Should I test Forky?
Thanks

EDIT: Well, I only installed SAMBA, DietPi Dashboard, FTP, and when copying 30gb of files, it crashed HARD:

For the first error, can you check that your system time is correct.

Thanks to chatgpt, I seemed to fix the fatal crash. I managed to copy 100gb (1 file!) and 30 700mb files without a crash.

Here is the solution:

Kernel Panic Under Heavy Samba Load on VIA Eden (Fixed)

Problem:
On a VIA Eden 3500U system running DietPi (Debian kernel 6.x), the server crashed during large file transfers (30–100GB over Samba). The kernel panic occurred in:

memcg_slab_post_alloc_hook

This indicates a crash in the memory cgroup (memcg) subsystem under heavy I/O and slab allocator activity.

Cause:
Kernel 6.x memory cgroups are unstable on some legacy VIA hardware under sustained load. Not a RAM or disk failure.

Solution:
Disable memory cgroups at boot.

Edit:

/etc/default/grub

Modify:

GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0"

To:

GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0 cgroup_disable=memory"

Then run:

update-grub
reboot

Result:
System became fully stable under 100GB sustained transfers at 100% CPU load.

This fix is safe if you’re not using Docker or container memory limits.
