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
