I found this out by disassembling the kernel code. That code has a
bug it in when the stuck case is hit - it fails to issue the log
force in that case, and that's why I've been seeing this kernel get
stuck. False alarm - will now try to reproduce without any dev
patches in the kernel.
Sad to here that ;-( I'm now trying to prepare a 160GB dd image for you
where it is reproducable.

The testimage is ready. I'm just packing it und uploading it. I'll send you all details via private mail.

Hope that helps.
