Re: Kernel Oops on alpha with kernel version >=6.9.x

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?
