Red Hat Bugzilla – Bug 7346
kernel do not recognize parallel port
Last modified: 2008-05-01 11:37:53 EDT
Description: I have running Red Hat 5.2 system with parallel port (and printer attached to him) working properly. I upgraded to Red Hat 6.1 and after trying to print something discovered that printer is not recognized by the system. I tried to add new printer using printtool and port probing failed. I have recompiled the kernel with printer support in kernel (prev. it was module i think). After booting new kernel tries to load printer driver but unsuccessful (see dmesg file). Next few lines are output from dmesg command after booting the system: Serial driver version 4.27 with MANY_PORTS MULTIPORT SHARE_IRQ enabled ttyS00 at 0x03f8 (irq = 4) is a 16550A ttyS03 at 0x02e8 (irq = 3) is a 16550A pty: 256 Unix98 ptys configured request_module[parport_lowlevel]: Root fs not mounted request_module[parport_probe]: Root fs not mounted lp: driver loaded but no devices found apm: BIOS not found. Real Time Clock Driver v1.09
add alias parport_lowlevel parport_pc to /etc/conf.modules.
