Description Philip Tuckey 2006-04-14 10:43:43 UTC

Fujitsu-Siemens Lifebook Ssomething
kernel 2.6.13-15.8-default

With pnpacpi=off, dmesg shows
parport0: PC-style at 0x378 [PCSPP,TRISTATE,EPP]
parport0: faking semi-colon
parport0: Printer, HEWLETT-PACKARD DESKJET 720C
lp0: using parport0 (polling).

Then configuring this printer with YaST works fine, and the same entries show up again in the log - I guess YaST unloads and reloads modules to search for printers.

Without pnpacpi=off, the parport is detected at boot (log as above except using interrupt instead of polling), however thereafter if parport_pc is unloaded then reloaded there is a log message saying that the parport pnp device (00:06) is disabled, and the parport doesn't work - YaST can't see the printer.
