Description of problem:
After installing Red Hat Linux 8.0 with all options, logging in as any user,
issuing startx, waiting for the load the complete, and attempting to use the
mouse results in a hard lockup of the system.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Load Alienware system with all options for Linux.
2. Log in as any user.
3. Issue the command startx.
4. Wait for load to complete.
5. Attempt to use the MS Intellimouse Explorer.
6. Attempt CTRL-ALT-Backspace and confirm that system is completely locked.
Actual Results: Needed to power down the unit. This involved either holding
the power switch down for 7 seconds or using the actual power switch on the
back of the unit.
Expected Results: I expected to be able to use the mouse in KDE.
I said the problem with with KDE, but I'm not convinced of that. The problem
persisted in Gnome. On my system, the problem even happened if I tried to
install Mandrake 9.0. The fix was to connect the mouse not to the USB port but
to the PS2 port. However, this results in much less mouse precision and
responsiveness, especially in games. The system is using an ASUS A7N266-C DDR
mobo and has 768Mb of 2100 DDR RAM, a Seagate 80Gb Barracuda drive a hda, a
Western Digital 80Gb drive as hdb, a Soundblast Audigy w/1394 soundcard, a
Lite-On 16x48xDVD ROM drive, a Lite-On 48/12/58 CD-RW, an Nvidia Ti4600
graphics adapter, and an AMD 2200+ processor. I've installed Linux on hdb and
have installed Microsoft Windows XP Professional on hda. It's working fine.
I should also note that I ran Red Hat 7.3 without problems on the same
hardware while the mouse was connected to the USB port. Something with the new
version of Red Hat 8.0 and Mandrake 9.0 is at the root of the problem.
Hmm, it's not KDE bug. it's a bug in kernel
This sounds like the same problem I am recieving. I am using an Asus A7N266-E
motherboard. Using any of the kernels in 8.0 and rawhide this problem occurs
except for the BOOT kernels. Plugging any USB device in while in a non-BOOT
kernel causes an immediate lock-up of the system.
I will be happy to provide further information as needed.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
