Red Hat Bugzilla – Bug 205864
USB hard drive invisible at boot
Last modified: 2007-11-30 17:11:42 EST
Description of problem:
On FC5, when I boot /dev/sdc5 shows up pointing to my external USB
hard drive, on FC6t2 with latest updates, there is no USB drive
in /dev/ when I boot - I have to unplug and plug back in for it to
show up (at which point I do see /dev/sdc5 just as in FC5).
Version-Release number of selected component (if applicable):
Aug 29 19:12:07 (yumex) Updated: udev.x86_64 095-8
Sep 01 19:47:44 (yumex) Updated: hal.x86_64 0.5.7.1-3.fc6
Sep 08 22:00:36 (yumex) Installed: kernel.x86_64 2.6.17-1.2630.fc6
(not sure if any other components might be relevant)
So far, everytime.
Steps to Reproduce:
1. boot system
2. see no /dev/sdc5
no disk device
I see the closed bug 201422 which implies that the additional rule fixes
problems like this, however, I checked my 05-udev-early.rules file and
it does indeed contain the rule 201422 talks about (it fact it is identical
with the FC5 version of the file), so whatever is going on wasn't fixed
This is a 500GB Maxtor USB 2.0 drive in case it matters.
On my FC5 system, I see this in the /var/log/dmesg file which appears
to have something to do with the USB hard drive:
ohci_hcd 0000:00:02.0: wakeup
scsi4 : SCSI emulation for USB Mass Storage devices
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
usb-storage: device found at 5
usb-storage: waiting for device to settle before scanning
On FC6t2, I see nothing in the dmesg file that gives any hint that
it has anything to do with the USB drive (and certainly none of the
messages above show up in any form).
Just installed FC6t3 and worked through a bunch of problems to get it where
it would boot, and found that the initial install from the DVD image has the
same problem with not recognizing USB hard drive.
However, once I ran yum and pulled in all the latest updates which got me to
the 2647 kernel, it does recognize the USB disk, so it looks like this is
probably fixed in latest devel versions.
