Description of problem:
hwbrowser does not show libata SATA drives.
They're just missing from the harddrive tab.
My other drives are there.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install SATA drive
2. configure kernel to use libata instead of IDE
3. look for it in hwbrowser
Are you running hwbrowser as root or not? For some reason, I see the
drives if I run it as root but not as a regular user. I wonder why
Ah, it is the call to parted.PedDevice.get() that is trying to access
/dev/sda, which is not allowed unless you are root.
After talking with some of the other developers, we should make
hwbrowser require the root password in order to run.
Oh wait, it already requires root priviledges to run.
Try this: As root, run 'kudzu --probe --class=HD' and attach the
output to this report.
[root@smirl jonsmirl]# /usr/sbin/kudzu --probe --class=HD

Shows kernel finding SATA drive
sata drive is not in /etc/sysconfig/hwconfig
Note that there are two ways to hook a SATA drive up in the kernel.
One way is via the IDE drivers. That way works with hwbrowser. The
other is the brand new libata scheme which works via the SCSI
subsystem. That one doesn't work.
You want to use the libata method; it works at full speed UDMA150/133,
the IDE scheme only works at UDMA33.
I definitely have a functioning /dev/sda device.
You might want to have a kernel person look at this bug too:
This is only broken in a 2.6 kernel.
2.4 works. Although I couldn't tell that until today since 2.4
wouldn't boot on my SATA drive until today. Dell issued BIOS patch
that fixes boot issue.
I am experiencing the same problem, but with my FDD. hwbrowser does
not show it and there is no entry in /etc/sysconfig/hwconf. The drive
works fine and the floppy module is loading on boot.
Should I file a new report or just leave this comment as an addendum
to this bug report?
Matt: file a new report.
Works for me with ICH5 SATA and current rawhide kernels... do you
still see this with newer kernels?
Still not there on up2date FC1. Right now I am running 2.6 kernel on
FC1. It appears if I use the IDE driver.
This works fine for me with FC2. Please reopen this bug report if the
behavior persists in FC2 on your machine.
