Description of problem:
On a fresh install of FC2, when booting the following appears in the
kernel output:

SCSI subsystem initialized
PCI: Found IRQ 10 for device 0000:00:0e.0
scsi0: <fdomain> No BIOS; using scsi id 7
scsi0: <fdomain> TMC-36C70 (PCI bus) chip at 0xe800 irq 10

If I try to mount /dev/sda1 the kernel reports that there is no device
there. Manually loading the module a second time (modprobe fdomain)
results in the same error again, but this time the device is available.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. modprobe fdomain
2. check /var/log/messages
3. observe kernel error messages

Comment 1 Dave Jones 2005-04-16 00:10:21 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
