Just opened up bugzilla 229831, you should be able to see it now.

Hi folks,

This bugzilla 229831 seems "restricted" :(  Can someone please forward
its details? I'm interested in understanding the actual problem and its

Meanwhile I'll try an upstream kernel. Should 2.6.21.rc1 be fine?

Thanks,
Sridhar
