For the last three or four version of SUSE (other Linux variants too) my old machine keyboard/mouse will lockup usually with in 5-30 minutes.
It it is an Intel D815EPEA2 motherboard. 512MB RAM
When it locks up I can often plug in a USB mouse and have that work but without a keyboard the system is useless.
Fascinating. I have an Intel D865PERL in one box (running SuSE Linux 10.0) and an ASUS P5B/Deluxe in another (running openSUSE 10.3). I recently replaced (tried to replace) a pair of keyboards and mice with a single keyboard and mouse (going from PS/2 keyboards to a USB keyboard, but the mice were USB before and after) connecting the mouse and keyboard via an IOGear 4-port DVI/USB KVM switch. When I use the KVM switch I get the same symptom you report, but only on the Intel board. The ASUS never has any problems. Other "fascinating" details of this problem: - The mouse and keyboard don't freeze simultaneously. - If I keep moving the mouse, it won't hang / stall. (It's possible this is the case with the keyboard, too, but I haven't tried to confirm that hypothesis.) - If when the mouse and / or keyboard are frozen I switch the KVM to the ASUS box, wait a while and switch back to the Intel box, the mouse and keyboard will work again for a while on the Intel box. - If when the mouse and / or keyboard are frozen I switch the KVM _quickly_ to the ASUS box and back to the Intel box, they will _NOT_ unlock. - There does not appear to be a fixed amount of time before the mouse and / or keyboard freeze. Sometimes it's a matter of 30 seconds, other times I can work OK for a few mintues, but never more than that. I've tried every variation of the BIOS USB legacy on/off full- / hi-speed, etc. settings on the Intel box to no avail. This is a most vexatious problem for me, 'cause with multiple keyboards on my desk, I frequently type on the wrong one and am often leaning over one to type on the other. I fear one day I'll type something on the wrong keyboard (the one _not_ connected to the display) and something bad will ensue. Lastly, this same setup (mouse and keyboard connected via KVM) also gave the ASUS box problems when it was running openSUSE 10.2, but in that case the problem was that when the KVM was switched away from that box, the kernel would periodically (and frequently) emit a huge bolus of USB-related diagnostic messages into /var/log/messages. This might have gone unnoticed, except for the fact that almost everything on the system paused while the messages were being emitted (possibly 'cause they were also going to virtual console 10).
I tried plugging a combo USB mouse and keyboard, but in the end I had a lockup as well. The same keyboard mouse combo works on other hardware platforms so this is unique to this hardware.
I am going to try the dreaded MS next to see if that will work.
Anyone have suggestions how I might further diagnose this or is it time to junk the machine?
I got nothing, but I'd dearly love to resolve this problem!
