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.
