Subject: serious bug / panic with nfsd/softdep (ubc?) (kern/11906?)

NetBSD 1.5S/i386 (of today, but this problem exists since several
weeks) as an nfs server for /usr/src (a kernel raidframe 1), which is
locally softdep mounted.
When using this directory mounted on a nfs client (in my case an
NetBSD/macppc) for compiling, this client crashes the above mentioned
server always exactly at the same 'make build' step, in my case when
building the libskey shared library:
panic: softdep-pageiodone: resid < 0, vp 0xe5dd98d4 lbn pcbp 0xe5c9108
Stopped in pid 143 (nfsd) at cpu_Debugger+0x04: leave
Using /usr/src locally on the i386 machine does not show this problem.
Mounting /usr/src without softdep 'solves' this problem.
-> Any further testing/debugging necessary? 'Cause I have a quite
reliable scenario to produce this panic...
