From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: My HP LaserJet 2100 printer stopped working after the kernel was updated from 2.6.9 versions to 2.6.10. CUPS can not locate the parallel port (/dev/lp0). Selecting 2.6.10-1.741_FC3 or 2.6.10-1.737_FC3 from grub, and running "dmesg | grep lp" gives: lp: driver loaded but no devices found Modules linked in: parport_pc lp parport autofs4 ipt_state ipt_REJECT ipt_limit ipt_LOG ip_conntrack_ftp ip_conntrack iptable_filter ip_tables microcode dm_mod video button battery ac md5 ipv6 uhci_hcd ehci_hcd i2c_i801 i2c_core snd_intel8x0 snd_ac97_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd soundcore snd_page_alloc tg3 floppy ext3 jbd ata_piix libata sd_mod scsi_mod Selecting 2.6.9-1.724_FC3 from grub, and running "dmesg | grep lp" gives: lp0: using parport0 (polling). lp0: console ready and the printer works. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Select a 2.6.9 kernel from grub. 2. Check that a parallel port is detected using dmesg - for me, it is. 3. Select a 2.6.10 kernel from grub. 4. See if a parallel port is detected using dmesg - for me, it isn't. Additional info:
