diskcorruption on 6.12.y

[folkertvanheusden]

Describe the bug

Revision 521f2ba of branch rpi-6.12.y gives massive disk-corruption when realtime-kernel is enabled.

Steps to reproduce the behaviour

Configure kernel for real-time.

Device (s)

Raspberry Pi Zero 2 W, Raspberry Pi 3 Mod. B

System

raspbian 64bit lite

Logs

Not directly available. If this problem is of interest, I can see if I can reproduce it.
Errors I saw were related to directory-nodes being full.

Additional context

No response

Realtime support is new to 6.12:

1. Have you add a non-corrupting 6.12 realtime kernel before the indicated commit?
2. Does a non-realtime build of 6.12 work for you?
3. Have you add a non-corrupting 6.11 realtime (with patches) kernel?
4. Have you tried realtime kernels before?

5. On which medium are you seeing corruptions - SD card or some external storage?

[folkertvanheusden]

1. no, it was the first I tried
2. seems to fail as well. see log below.
3. no
4. no. the RT patches were only merged in 6.12 I believe.
5. sd cards (I tried 3 different cards, all 32 GB in size)

Both the realtime and non-realtime 6.12 kernel fail:
