Using kernel 2.6.9-gentoo-r1 when lp is loaded it reports "lp: driver loaded but no devices found" The parallel port does show up in /proc/ioports as "0378-037a : winbond parport" Reproducible: Always Steps to Reproduce: 1. use kernel 2.6.9-gentoo-r1 with parallel support loaded into kernel or as module 2. modprobe parport_pc (works) 3. modprobe lp Actual Results: dmesg reports: lp: driver loaded but no devices found Expected Results: reported a port found and assigned it to lp0 /proc/ioports: 0000-001f : dma1 0020-0021 : pic1 002e-0030 : winbond_check 0040-0043 : timer0 0050-0053 : timer1 0060-006f : keyboard 0070-0077 : rtc 0080-008f : dma page reg 00a0-00a1 : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 0376-0376 : ide1 0378-037a : winbond parport 03c0-03df : vga+ 03f6-03f6 : ide0 03f8-03ff : serial 0cf8-0cff : PCI conf1 a000-afff : PCI Bus #01 a000-a0ff : 0000:01:00.0 b000-b0ff : 0000:00:0c.0 b400-b407 : 0000:00:0f.0 b400-b407 : sata_via b800-b803 : 0000:00:0f.0 b800-b803 : sata_via bc00-bc07 : 0000:00:0f.0 bc00-bc07 : sata_via c000-c003 : 0000:00:0f.0 c000-c003 : sata_via c400-c40f : 0000:00:0f.0 c400-c40f : sata_via c800-c8ff : 0000:00:0f.0 c800-c8ff : sata_via cc00-cc0f : 0000:00:0f.1 cc00-cc07 : ide0 cc08-cc0f : ide1 d000-d01f : 0000:00:10.0 d000-d01f : uhci_hcd d400-d41f : 0000:00:10.1 d400-d41f : uhci_hcd d800-d81f : 0000:00:10.2 d800-d81f : uhci_hcd dc00-dc1f : 0000:00:10.3 dc00-dc1f : uhci_hcd e000-e0ff : 0000:00:11.5 e000-e0ff : VIA8233 e400-e4ff : 0000:00:12.0 e400-e4ff : via-rhine dmesg snippet: lp: driver loaded but no devices found From Linux-kernel: http://www.ussg.iu.edu/hypermail/linux/kernel/0410.2/0216.html On Mon, 2004-10-18 at 12:51, Thomas Maguin wrote: > The parallel printer disappears from 2.6.9-rc2 to rc4. > > lp: driver loaded but no devices found > > The rc-1 and rc4-mm1 versions are ok. It looks like the patch from Olaf Hering <olh@xxxxxxx> http://www.ussg.iu.edu/hypermail/linux/kernel/0408.0/0792.html causes the problem. A patch from Andrea Arcangeli <andrea@xxxxxxxxxx> http://www.ussg.iu.edu/hypermail/linux/kernel/0409.3/1515.html corrects the problem. It looks like the Linus tree only has Olaf's patch. Andrew's tree (mm) has Andrea's patch.
Same problem with kernel-2.6.9-gentoo-r1
also with gentoo-dev-sources-2.6.9-r6
still a problem?
