Hi;
With my longstanding configuration, kernels upto 6.6.9 work fine. Kernels 6.6.1[0123] and 6.7.[01] all lock up in early (open-rc) init, before even the virtual filesystems are mounted.
The last thing visible on the console is the nfsclient service being started and:
Call to flock failed: Funtion not implemented. (twice)
Then the machine is unresponsive, numlock doesnt toggle the keyboard led, and the alt-sysrq chords appear to do nothing.
The problem is solved by changing my 6.6.9 config option:
# CONFIG_FILE_LOCKING is not set to CONFIG_FILE_LOCKING=y
(This option is under File Systems > Enable POSIX file locking API)
I do not recall why I unset that, but it was working for I think the entire 6.6 series until 6.6.10. Anyway thought I would mention it in case anyone else hits it.
