View Full Version : changed CD drive, now FC hangs loading Gnome desktop

I have a machine with FC1 which has been working fine. I decided to replace the CD-ROM drive with a CD-R/W drive today, and now I can't get into the Gnome desktop. I get the normal FC login window, I enter my login and password, then FC hangs when it gets to the point it is loading the CD Device Handler. It requires a hard reset or power off, even the mouse pointer is frozen. CTRL+ALT+backspace has no effect. It appears it is not just X which is hung, but the entire machine.

I can get in using a KDE session or the failsafe console, but not Gnome.

Edit: At least I got in using KDE once. The second time it also locked up like Gnome.

I have all updates installed, as of yesterday night, including the latest kernel. The machine has a full install of FC1 (everything). Here is the hardware:

AOpen AX34-U motherboard (VIA 694T chipset)
PIII-733
768MB PC133 SDRAM
30GB Maxtor, primary/master
HP CD-Writer 8200+ secondary/master (replaced Lite-On 52x CD-ROM)
3.5 floppy
ATi Radeon 8500 64MB (ATi 3.2.8 driver)
Ensonic ES-1371 AudioPCI soundcard
3Com 3C905B-TX nic

The HP burner has previously been used under every major RH version starting with 6.2, with no problems. I am sure it's not a hardware problem, but rather a configuration in FC1 which does not like the previous CD drive replaced with this CD-RW drive.

The machine has been rock-solid stable since installing FC1 a few weeks ago, including occasionally leaving it running for a few days. I haven't yet tried to put the original CD-ROM drive back in the system.

How can I fix this?

You'll want to look around in /var/log/messages -- somewhere in there will be some errors from your hardware, probably near the bottom. You can use the failsafe terminal as root to read it.

Hmmm... finally got around to cheking the messages log. No help there. The drive seems to be detected properly (shows proper id string), and no errors that I can see related to the drive itself or IDE in general.

I figured something was just pooched in the OS, so I will just re-install (clean, no important data on this box yet). So I boot from the CD, and it hangs running /sbin/loader off the HP CD-RW drive. Tried warm boot, cold boot, disconnect and reconnect drive cables, still hangs in the same place booting from the CD. So, I put the original CD-ROM drive back in, removed the HP CD-RW. Everything works. Now, I try putting the HP drive in as secondary slave (same channel as CD-ROM). Back to the same, hangs at login at the CD device handler icon.

Not sure if it's a pure compat problem between Fedora and this partular drive, or if something has just gone bad in the drive since last time I used it. It was used most recently in a RH 9.0 system, where it was fine. I'll have to drop the drive in another box and check it with another OS to see if it's hardware.

Try booting with the nodma argument.

hi,

I am having the same problem

has anyone found a remedy?

I've tried the "nodma" argument and this doesn't seem to work

Thanks,
mattmatt

edit: upon further investigation it appears to be an usb 2.0 issue

when disabled it continues as it should
