We have at least 10 of these boxes. All that run SUSE had this same issue. Mandrake boxes run fine. Our fix was acpi=off which seemed to help. The pauses seemed to be sometimes related to disk access -- Adaptec AIC7902 with Seagate ST373307LW Yes this appears to be a kernel problem that needs to be looked at. eric Bernard Lineham wrote:
Hi,
We have two of the same workstations (W1100z) and we are seeing exactly the same problem as described in Mark's e-mail under Suse 9.3. The problem also occurs under Novell Linux Desktop. I can also add Fedora Core 4 and Ubuntu 5.04 to the list of distros that work properly. This is definitely a compatibility issue with Suse only.
Suse is the distribution of choice at our institution and this problem is proving to be very frustrating. I would welcome any suggestions as to how we might work around it.
Cheers,
Bernard

I got a similar problem with the keyboard. I believe it was related to a timing issue, caused by some problems with the interrupts. For instance, time was not linear on this machine, it keeps jumping back and forth all the time. Very odd behavior, the OS was really confused. With APIC disabled in the BIOS and some kernel updates, it got better...

Hardware: 4 different Sun Java Workstation W1100z (Opteron 150, 1GB RAM) 4 x Sun USB keyboard 4 x Sun USB mouse
Problem occurs with: SuSE Professional 9.1 64bit SuSE Professional 9.3 32bit SuSE Professional 9.3 64bit
Problem does not occur with: Sun Java Desktop Gentoo OpenBSD
Problem Description:
Keyboard - While holding down any key, that character will repeat on the screen about 30-160 times until it pauses for a second before displaying several of the same character at once, and will then continue to repeat until the next pause. This occurs on the console, in xterms, remotely, in different shells, and in different editors. It also occurs while typing normally.
Mouse - While in X, moving the mouse in circles for about 10s-60s, the mouse will pause for a second and then jump to where it thinks it should be. If I continously move the mouse in circles it will pause just about every minute.
I've only had the problem occur in SuSE Professional, 9.1 64bit, 9.3 32bit, 9.3 64bit. I didn't encounter the problem in the Sun Java Desktop, gentoo or in OpenBSD. The problem occurs using the latest SuSE kernel, as well as with kernel 2.6.13-rc1. We currently have 4 W1100z's that have SuSE 9.3 Pro 64bit on them, and all 4 exhibit the same problem.
Thanks in advance for any help. If you need more information let me know.
