B/W G3 Traps on USB.Mouse in OS X (10.1)

[[Scizo]]

Every now and then my B/W Rev. 1. traps with the USB.mouse module.
It always happens when i'm moving the mouse (duh) .

The problem is there regardless of the version of OS X i'm using.. i've tried 10.1, 10.1.3, 10.1.4, 10.1.5.. always the same!

I've tried a bunch of things... replacing the disk, (re)moving memory sticks, replacing the mouse, using another USB port... and nothing seems to work

Of course i cant remember the full trap dump, but the mouse module is _always_ the top module, followed by the USB module etc...

Does anyone have a clue as to what is happening ?

hmm... since noone seems to have heard about this bug (or doesnt recognize it!), i took the time to _manually_ write down the trap message...
If i just keep my hand away from the mouse, everything is rock solid... but when using the mouse i get crashes sometimes as soon as the login screen!

here goes :

I think i've solved it ... i reinstalled 10.1 again, and followed the update path from 10.1.3-combo, 10.1.4 and software update for 10.1.5... still the same problem..
I then read on apple.com's newsgroups that software update would sometimes fck up your downloads if downloaded over a slow link (mine is 256/128)..
so i got the 10.1.5 combo update, and put it on top of my current 10.1.5 installation... and guess what.. I havent seen the USBMouse trap all day (would occur at 5-10 mins intervals before)
Mabye worth a try for all other people with 10.1.5 problems!

It's interesting how, as code bases become much larger and modular/independent of eachother, how many tiny bits of it can become corrupted without it being apparent.

Back in the day, I remember downloading Winzip like 6 times because my 2400 baud modem was so dog slow. Grrrr....

Aren't error correction and TCP/IP supposed to fix problems like that?

hmm... aparently it didnt _FIX_ the problem.. my box just pulled another USBMouse trap yesterday...
But it's definatly more stable now! ... "only" two crashes i as many days!

99.99% of the time, yes. However I have had very rare occurences when a particular file corrupts when going over certain lines - usually dependant upon the way that the line compresses the data. We actually managed to track this down with the help of IBM (using MQseries) so TCP/IP can't help all the time.

Certain files may be more susceptible to this than others - just depends on how they are packed. I am not suggesting necessarily that this is what we are seeing - it is just a possibility.

Hmmm... the USB trap didnt go away .. i guess i was just lucky..
I did however come across the following article at apple.com http://kbase.info.apple.com/cgi-bin.../query?searchMode=Expert&type=id&val=KC.75016)
It fixed the error... OS X is still unstable as h*ll, but at least i got rid of the USB trap.
My most frequent crash is now that the entire screen freezes.. i can tell from my switch that theres still network traffic going in/out of the box, but mouse and keyboard doesnt respond anymore.
