| |
Hello, I've noticed that parallel port stopped working for me with 2.6.9. It works with 2.6.8.1 using the same .config - the relevant part: CONFIG_PARPORT=y CONFIG_PARPORT_PC=y CONFIG_PARPORT_PC_CML1=y # CONFIG_PARPORT_SERIAL is not set CONFIG_PARPORT_PC_FIFO=y CONFIG_PARPORT_PC_SUPERIO=y # CONFIG_PARPORT_OTHER is not set CONFIG_PARPORT_1284=y
I've noticed that there's "smsc parport" instead of parport0 in /proc/ioports and new smsc_check range but the 0778-077a range is no longer there. My board has SMC Super I/O chip.
Here's "diff ioports-2.6.8.1 ioports-2.6.9" output: 3c3,4 < 0040-005f : timer --- > 0040-0043 : timer0 > 0050-0053 : timer1 19c20 < 0378-037a : parport0 --- > 0378-037a : smsc parport 22a24 > 03f0-03f2 : smsc_check 25d26 < 0778-077a : parport0 29c30,33 < 4008-400b : ACPI timer --- > 4000-4003 : PM1a_EVT_BLK > 4004-4005 : PM1a_CNT_BLK > 4008-400b : PM_TMR > 400c-400f : GPE0_BLK
I also see some new ACPI errors during 2.6.9 startup: ACPI: Subsystem revision 20040816 ACPI-0205: *** Error: Return object type is incorrect [\_SB_.PCI0.ISA_.UAR1._PRW] (Node c7f89f40), AE_TYPE ACPI-0205: *** Error: Return object type is incorrect [\_SB_.PCI0.ISA_.UAR2._PRW] (Node c7f89e20), AE_TYPE ACPI-0205: *** Error: Return object type is incorrect [\_SB_.PCI0.ISA_.LPT_._PRW] (Node c7f89c40), AE_TYPE
and this: parport: PnPBIOS parport detected. pnp: Device 00:0e disabled.
In 2.6.8.1, it's correct: parport: PnPBIOS parport detected. parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,ECP,DMA] lp0: using parport0 (interrupt-driven).
If more details are needed, just ask.
