Interrupt storm detected on "irq7: lpt0"

[Willem Jan Withagen]

I think I tried that one, but it did not work. I still have that flag 
standing.
Now that is a long time ago, and this could be done without rebooting 
the server.

dmesg:
ppc0: using extended I/O port range
ppc0: ECP SPP ECP+EPP SPP
ppc0 port 0x778-0x77b,0x378-0x37b irq 7 drq 3 on acpi0
ppc0: SMC-like chipset (ECP/EPP/PS2/NIBBLE) in COMPATIBLE mode
ppc0: FIFO with 16/16/9 bytes threshold
ppbus0: <Parallel port bus> on ppc0
ppbus0: IEEE1284 device found /NIBBLE/ECP/NIBBLE_ID/ECP_ID/Extensibility 
Link
Probing for PnP devices on ppbus0:
ppbus0: <Hewlett-Packard HP LaserJet 2100 Series> 
PJL,MLC,PCL,PCLXL,POSTSCRIPT
lpt0: <Printer> on ppbus0
lpt0: Interrupt-driven port

I'll give it a shot for the next reboot.

Major difference I see is that you've got the device on isa0 whereas 
mine is on acpi0
