We have seen it on at least 3 different controllers from at least 2 different vendors (I do not know, what hardware Gu has). So, for now, it looks like to happen on more different controllers than not.
Testing environment - uhm, what shall I say? On each of the two notebooks affected runs 64bit openSuSE 11.4 in more or less default configuration (apart from kernel, of course).
Just do a "ls -lR /" and watch kernel log while plugging/unplugging power.
Maybe running a 64bit system/kernel is part of picture? As far as I can see all affected machines run 64bit.

I've at least one machine available where I can test. So, if there is anything (preferably non destructive ;-) ) you want me to test this should be possible.
Maybe I'll have a look if my netbook (running 32bit) is also affected.
