Hi Ingo, I'm testing a new realtime kernel and I'm getting tons of
these. I got two complete freezes (no sysrq response) since I started to
test yesterday, but I have no way of knowing whether these reports are
related to the freezes.
Kernel i686: 2.6.24.6 + 2.6.24.4-rt4 (with three chunks tweaked to
patch) + almost all realtime mrg kernel revision 47 patches + compatible
fedora patches from 2.6.24.4-85.
I'm including some of the "BUG" reports, let me know if you want more.
(please cc me, I'm not reading the list right now)
