(FLOPPY PCI)can't access floppy after RH 8.0 install

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.0.1) Gecko/20021003 Description of problem: After installing RH8.0 from cdrom the floppy drive cannot be accessed from linux. When I attempt to mount the floppy with, say, a driver disk in the floppy: mount /dev/fd0 /mnt I get mount: /dev/fd0 is not a valid block device I can use the floppy drive just fine when I boot Win 98SE. Also, during the installation, the creation of a boot disk failed. I also noticed that the addresses assigned to my primary IDE controller were not quite right: kenyatta~$ cd /proc kenyatta/proc$ cat ioports 0000-001f : dma1 0020-003f : pic1 0040-005f : timer 0060-006f : keyboard 0070-007f : rtc 0080-008f : dma page reg 00a0-00bf : pic2 00c0-00df : dma2 00f0-00ff : fpu 01f0-01f7 : Micron FDC 37C665 02f8-02ff : serial(auto) 0330-0331 : mpu401 0332-0337 : SoundScape 0378-037a : parport0 037b-037f : parport0 03c0-03df : vga+ 03f4-03f7 : Micron FDC 37C665 <== This should be 03f6-03f6 !!! 03f8-03ff : serial(auto) 0534-0537 : SoundScape PNP 0cf8-0cfb : PCI conf2 e000-e0ff : ATI Technologies Inc 3D Rage Pro 215GP f800-f8ff : Accton Technology Corporation SMC2-1211TX f800-f8ff : 8139too fc00-fcff : Adaptec AIC-7892A U160/m At boot time, the floppy appears to be busy: Floppy drive(s): fd0 is 1.44M, fd1 is 1.2M floppy0: Floppy io-port 0x03f2 in use In /proc/ioports, The primary IDE device appears to be using part of the I/O space of the primary floppy. In fact, the identification of the PCI IDE device as a "Micron FDC 37C665" is strange. I have an Intel Premiere/PCI-II (Plato) mother board. The primary IDE device is a PC Tech RZ1000. It is a PCI device. The board also has a Standard Microsystems Corporation FDC 37c665 super IO controller. This controller provides two serial ports, one parallel port, a floppy controller and an ISA IDE controller that is the secondary IDE device. I created a boot disk in Win98SE using rawrite. I can boot from the floppy but I cannot use a driver disk. If a boot from a RH8.0 boot disk and use the RH8.0 CD rom, when I use Control-Alt-F2 to enter the shell, I cannot use the floppy. If I boot from a RH7.2 boot floppy and use the RH8.0 CD-rom, when I enter the shell, I can use the floppy OK and /proc/ioports shows the primary IDE device using only ports 0x1f0-ox1f7 and 0x3f6. This problem appears to be similiar to bug reports 69048, 76513 and 77886. Please help. I can provide any additional information required. Ken Riley khriley@ameritech.net I have both IDE controllers busied out in the BIOS since I have an all SCSI system. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Boot RH8.0 linux 2. put a formatted disk into the floppy drive 3. As root, type: mount /dev/fd0 /mnt Actual Results: I get the error message: mount: /dev/fd0 is not a valid block device Expected Results: The floppy should have been mounted onto the /mnt mount point. Additional info: This happened with the Red Had Linux 8.0 Professional retail distribution. The kernel is 2.4.18-14. I have since upgraded to 2.4.18-19.8.0 and still have the same problem.
Created attachment 89328 [details] Boot messages captured at serial console At the LILO "boot:" prompt, I added floppy=debug to see if I could get more verbose output for the floppy problem. I didn't.
