Created attachment 1883 [details] Full kernel log from 2.6.1-bk4 I'm attaching a full kernel log from 2.6.1-bk4 in case more information is necessary (it's from a serial console)
It's present in -bk5, but it apparently is gone in -mm5 (I've not tested -bk6 yet).
Is this fixed in the latest kernels?
Seemingly, yes. I've not tested kernels later than 2.6.4-rc1-bk2 yet, however, because of the Bug # 2240 (now that I have a fix, I'll let you know as soon as I do this).
As far as I can say, it is fixed in the 2.6.4 kernel.
