Me too, and when it's compiled in the kernel, it boots, but it hangs
when I start acroread7. I think remember that the kernel built from
the source as of May 24 was OK.

I need something I can duplicate from a freshly installed machine.
    I need to know which packages I need to install and a sequence of 
    commands that reproduces the problem.

If linux emulator is compiled in, just install pkgsrc/emulators/suse_base
and run
$ /usr/pkg/emul/bin/ls -l
and it never returns. You may have to run `sysctl kern.sync_on_panic=1'
in advance, as panic command from DDB may be stuck.
If linux emulator is not compiled in the kernel, loading it via
/etc/rc.d/abi will trigger the lock up(probably because it runs
/compat/linux/sbin/ldconfig).

I couldn't drop in to DDB on my SMP machine, but I could on my laptop.
I'm uploading a kernel dump on my leaf account.

Ok, I've just committed a fix for that issue.

Thanks, so far it doesn't lock up. But I don't understand why it
worked without looking at eofflag.

I'm not sure why it worked before either.  The algorithm in the linux
    readir code was clearly broken.  Any situation where a readdir returns
    just one cookie which happens to have an offset before the requested
    offset would have triggered the bug.
