Updating the machine's kernel from v5.19.x to v6.0.x causes the machine to not successfully boot. The machine boots successfully (and exhibits stable operation) with version v5.19.17 and multiple earlier releases in the 5.19 line. Multiple releases from the 6.0 line (including 6.0.0, 6.0.3, and 6.0.5), with no other changes to the software environment, do not boot. Instead, the machine hangs after loading services but before presenting a display manager; the machine instead shows repetitive hard drive activity at this point and then no apparent activity. ''uname'' output for the machine successfully running v5.19.17 is: Linux [MACHINE_NAME] 5.19.17 #1 SMP PREEMPT_DYNAMIC Mon Oct 24 13:32:29 2022 i686 Intel(R) Atom(TM) CPU N270 @ 1.60GHz GenuineIntel GNU/Linux The machine is an OCZ Neutrino netbook, running a custom OS build largely similar to LFS development. The kernel update uses ''make olddefconfig''. #regzbot introduced: v5.19..v6.0 --- Dominic Jones jonesd@xxxxxxxxxxxx
