I've found quite a bit of information about how to deal with:
"Interrupt storm detected in "irq7:"; throttling interrupt source"
Problem is, it's a little confusing.
From what I've gathered, the options are:
Use the BIOS to set the printer port to ECP,
Use lptcontrol to set the port to polled mode,
Use device.hints to do both
IIRC, in the past, I have used lptcontrol to set polled mode, but
that resulted in:
"too many stray irq7's, not logging any more"
Can anyone suggest a method to make both "interrupt storm" and "too
many stray irq7's" go away?
I always set to EPP in BIOS and device.hints to 0x24 (used to compile
into kernel pre 5.X). (I suspect one or the other would do, and ECP
would do instead of EPP, or 0x28 instead of 0x24). Haven't had an
interrupt storm or stray interrupt since. man ppc for the flags to use
and get into practice converting hex to binary and vice versa :-) Never
used lptcontrol.
