Description Jan Sembera 2004-10-27 05:03:09 UTC
Since I updated kernel from gentoo-dev-sources-2.6.8-r10 to gentoo-dev-sources-2.6.9-r1, kernel fails to detect parallel port and therefore I cannot use my printer. Booting back to 2.6.8-r10 fixed the problem, so I assume this should not be my fault. Configuration of 2.6.9-r1 kernel is attached. Relevant log messages follow

2.6.9-r1 bootup: 

Oct 23 11:05:04 graybox kernel: parport: PnPBIOS parport detected.
Oct 23 11:05:04 graybox kernel: pnp: Device 00:0b disabled.
Oct 23 11:05:04 graybox kernel: lp: driver loaded but no devices found

2.6.8-r10 bootup: 

Oct 16 07:26:00 graybox kernel: parport: PnPBIOS parport detected.
Oct 16 07:26:00 graybox kernel: parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT, EPP,ECP,DMA]
Oct 16 07:26:00 graybox kernel: lp0: using parport0 (interrupt-driven).

Reproducible: Always
Steps to Reproduce:
1. Boot gentoo-dev-sources-2.6.9-r1 kernel

Comment 2 Daniel Drake (RETIRED) gentoo-dev 2004-10-27 07:31:14 UTC
Could you please try development-sources-2.6.9 and 2.6.10-rc1 ? I think this is an upstream issue, would be interested to know if it is fixed.
Comment 3 Jan Sembera 2004-10-27 10:54:00 UTC
Looks like it. Vanilla 2.6.9 shows exactly the same behaviour I described, while 2.6.10-rc1 looks fixed. 
Comment 4 Daniel Drake (RETIRED) gentoo-dev 2004-10-27 15:17:34 UTC
Great, thanks for testing. Sorry to place another request on you, but could you please try applying the following patch to gentoo-dev-sources-2.6.9-r1|src/|src/drivers|src/drivers/parport|hist/drivers/parport/parport_pc.c

I think it's the one that fixes the problem, but would like confirmation before I add it to gentoo-dev-sources. Thanks :)
Comment 5 Jan Sembera 2004-10-27 16:30:57 UTC
I applied the patch and it appears that it solved the issue. Thank you for your great work on dev-sources. 
Comment 6 Daniel Drake (RETIRED) gentoo-dev 2004-10-27 17:09:38 UTC
Thanks for the speedy testing. I'll include this in the next release.
