I installed a PCIe board on debian 12 linuxcnc 2.9.4 and even though it works perfectly I get this error at the start of linuxcnc.
Is there a way to delete the message?
thanks

Had the same issue yesterday, PCI-E Sunix card, works perfectly but the error shows up whenever LinuxCNC is started.
Did not bother with it, but i did notice LSPCI does not show loaded module for it at all, but it does show all the other info with addresses and stuff.

As the message says it's not really an error, I think the only way to stop the message would be to modify the hal_parport code, or I not sure if this would work but add a debug level when loading the driver. First would work but means compiling Linuxcnc one's self the second option is just a guess.
If the machine works I wouldn't bother too much about it. Yeah it is a little annoying. But then again you have the convenience of CNC :)

The non-native parallel port is a parallelized serial port. The Linux kernel takes it as a serial PCIE port. That's where linuxcnc comes into conflict and raises the alarm. The older parallel port PCI expansion boards were neater and sent the OS the message (I'm a parallel port). This Generation does not, that is why this alarm appears that tells us (continue, it may not be a mistake). The issue is that linuxcnc starts in a messy way and I would like to solve it.

Yeah, this deserves a log file entry for debugging, but not an error pop-up...

So far i would think this is hardware related or blacklisted, the same card i removed from another PC that does not complain about it.
The warning PC had a PCI to parallel card and up to yesterday was working fine, for years, two days ago it was shut down as usual and yesterday morning it could not find the PCI card although LSPCI show it and the addresses and everything, but does not show kernel module nor kernel driver in use.
I have a stinking suspicion the card is being blacklisted, but i had no time to check as it was 11:30PM and the client was waiting for it (with his friends) and they are some 90KM far.
Nor did i try to modprobe, i could have done that, cr@p, but i forgot as i was poised at fixing it promptly.
