I'm still seeing this issue with 2.6.25 whenever I print a document. Any chance someone can take a look at it?
My previous analysis revealed it is an ancient essentially harmless bug that in the kernel, that my recent sanity checks have uncovered. I have been so busy I have not had a chance to look at it further and it appears no one else has either :( I would like to look at this but I don't know when I will get the time to dig deep enough into the generic parallel port code to do something about this. Thanks for the reminder. Now I at least have it in my memory of things that something should be done about list.
Thanks for the reply Eric. I do understand, but I hope you'll agree that having your syslog and inbox (through logcheck) spammed with these errors every time you send a print job is not very nice. Luckily I don't don't print very often nowadays :-)
Iḿ also seeing something similar. I run a customized ham radio printer port controller and the latest Ubuntu upgrade causes hundreds of errors until the server locks due to a memory leah. I have now disabled the service which poles the printer port, but obviously I would like to get the software working again. sysctl table check failed: /dev/parport/parport0/devices/ppdev0/timeslice Sysctl already exists Derek Vk5tcp
