Hi again, I did a bisec on gcc and found that if commit 3b9b8d6cfdf59337f4b7ce10ce92a98044b2657b is NOT applied will generate faulty code in the RCU implementation on alpha. The code fails since the when the fram pointer register is used for accessing local variables the stack gets corrupted. When the commit is applied, which it is in GCC-15.0.0 from 25th of june 2024 the gcc compiler will generate good code on alpha which mitigates both the rcu_expedited() bug (network interface renaming) as well as the scsi module unload bug. Not sure but GCC versions from 10.x to 14.x seem to suffer from this. Maybe this commit can be back ported to those versions? /Magnus
