Use of parport messed up in 2.6.5-2
Hi,
after having upgraded the kernel-image to 2.6.5-2 (ii
kernel-image-2.6.5-1-k7 2.6.5-2) with the last upgrade I cant use my
parallel port any more. I dont get any erro messages but the simpler
simply does not get any data. Cups accepts the printjob and immediately
says it is completed.
When booting I get the follwoing messages:
Apr 26 18:11:21 ds9 kernel: parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE]
Apr 26 18:11:21 ds9 kernel: parport0: Legacy device
Apr 26 18:11:21 ds9 kernel: parport_pc: Via 686A parallel port: io=0x378
Apr 26 18:11:21 ds9 kernel: parport: PnPBIOS parport detected.
Apr 26 18:11:21 ds9 kernel: pnp: Device 00:0a disabled.
What strikes me is the "disabled" in the last line. (Parallel Port is
_not_ disbaled in my BIOS and printing under windows works fine.) Now
when I manualle unload the modules lp, parport_pc and parport and the
reload them again, /var/log/syslog shows the following:
Apr 26 18:17:06 ds9 kernel: pnp: Device 00:0a disabled.
Apr 26 18:17:06 ds9 kernel: parport_pc: Via 686A parallel port disabled in BIOS
Apr 26 18:17:06 ds9 kernel: pnp: Device 00:0a activated.
Apr 26 18:17:06 ds9 kernel: parport: PnPBIOS parport detected.
Apr 26 18:17:06 ds9 kernel: parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,ECP,DMA]
Apr 26 18:17:06 ds9 kernel: parport0: Legacy device
Apr 26 18:17:06 ds9 kernel: lp0: using parport0 (interrupt-driven).
Again it says, that parport was disbaled in BIOS, which is NOT the case,
but at least line 3 says device activated. When I now want to print all
works fine. Now even ECP is detected
Is there any reason for this strange behaviour? And is there any way to
solve this problem but reloading the modules manually after each boot?
I found this in the changelog for 2.6.5-rc3 [1]
<ambx1@neo.rr.com>
[PARPORT] Update PC Parport Detection Code
This patch updates the parport_pc driver's probing code to better
detect PnP devices. It also removes an extra MODULE_AUTHOR.
Is there any hope that thing will be better in 2.6.5-3?
Hope anyone can help
TIA
Christian
