I dunno, memory corruption?

  It turns out that there was a mistake in my report, sorry.
The error occurs on 2.6.21-rc5 + patch-2.6.21-rc5-rt12 + my patches,
but it does not on 2.6.21 + patch-2.6.21-rt1 + my patches (except spindernet one).

  I thought I had checked it before sending the patch, but looks like I didn't.

  My appologies...
