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. > Well, the system I can reproduce it on is a production one, so I can't > really test too much on it. What exactly would you like to do? 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. -- MfG, Michael Leun -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
