interrupt issue, storm on parallel port, 5.4

[dave]

Hello,
    I've got a printserver that has an hp deskjet printer attached via
parallel port. I just got an email with the following message:

Interrupt storm detected on "irq7: lpt0"; throttling interrupt source

I've checked lpt0 in dmesg and this error didn't come up then, do i have to
worry about this? This is on a 5.4-p1 system, if so is there a fix?
Thanks.
Dave.
