In the /var/log/messages file there is following messge: "linux kernel: DMA write timed out". The message was being output every ten seconds from initial boot but it stopped in the middle of the night last night. Can anyone tell me what would have caused the message?
No clue. DMA is associated with hard drives and cd/dvd drives. Check in YaST/Hardware/DMA settings.
I cannot get the printer (HP LaserJet 4) to function. The following error messages are being sent to /var/log/messages when I try to lpr: unable to open /var/run/hpiod.port: No such file or directory: prnt/hpijs/hplip_api.c 75 unable to connect hpiod socket 50000: Connection refused: prnt/hpijs/hplip_api.c 693 unable to send ProbeDevices: Broken pipe
I believe the hpijs drivers is for InkJets not lasers. Go back into YaST/Hardware/Printer and choose the other driver for LaserJet 4.
Upon further investigation I've found that the printer problem I'm having and the DMA messages I'm getting are related. When I take the printer off-line the DMA timeout messages stop.
I'm still no closer, though, to getting the printer working. I've tried every HPLJ 4 (and related) driver. I get the same error messages to /var/log/messages (as noted above) when attempting to print with every driver.

What is the exact model of HPLJ4 that you have? Yesterday I helped a client hook up a LaserJet 4. They had to change to the "Laserjet 4 ljet4" driver from "Laserjet 4 hpijs" and then it took right off on SUSE 9.3 Pro. I don't anticipate any real differences between this and SUSE 10.0 Retail/OSS. The DMA being related to a parallel printer issue is interesting. Don't see how it could be related. Stan
