Description of problem:
In my HP xw8000 workstation (two Xeon 3.06 MHz processors with 1 GB
RAM) USB doesn't work at all with kernel-2.6.5-x and later. Boot hangs
if any usb devices is connected to computer. When usb devices are
connected AFTER the boot, no reaction can be seen.
dmesg reports the following error messages:
kernel: uhci_hcd 0000:00:1d.2: host controller process error,
something bad happened!
kernel: uhci_hcd 0000:00:1d.2: host controller halted, very bad!
No usb devices are recognized by the usb host controller as it can be
verified examining the contents of /proc/bus/usb/devices.
On the other hand, the kernel used by FC2 during the installation
works very fine. The only difference between installation kernel and
runtime kernel is that modules are compiled for i586 processor and not
Re-compiling the kernel using the kernel-2.6.x-i586-smp.config as
base, all work fine.
Only the following error messages is reported by dmesg when using
updfstab: Using deprecated /dev/sg mechanism instead of SG_IO on the
Anyway, USB works fine.
Version-Release number of selected component (if applicable):
kernel-2.6.5-x and later versions
Steps to Reproduce:
1. Boot using original Fedora's kernel-2.6.5-x and later versions
Actual Results: usb doesn't work at all.
Expected Results: Normal usb working

Created attachment 103384 [details]
Report of dmesg, content of /proc/bus/usb/devices and output of lspci
The attachment reports the output of dmesg and the content of
/proc/bus/usb/devices both for original FC2 kernel-2.6.5-1.358smp and
The output of lspci is also reported for sake of completeness.
The re-compiled kernels-2.6.x-y.zsmp-i586 need to be loaded by
generating the suitanle initrd file in order to load FIRST the SCSI
modules and THEN the USB ones.
Otherwise, SCSI crashes after usb devices are connected.
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.
