 Same problem when upgrading from Legacy 4.11 to 5.4 on our Intel STL2 
 server board.
 
 
 Tried:
    1. acpi0 and isa0 driver module
    2.  all possible hint.ppc.0.flags (with irq enabled)
    3.  all possible bios configs (nibble, centronics, ECP, EPP). Even 
 upgraded bios.
    4.  various modes on printer (normal, high-speed, auto, nibble)
   
 Pool mode partly solves the problem as the CPU is overloaded with LPD jobs.
 
 Again. This was not the case when running 4.11
