I have no crashes but i see locks of gbde file systems (no more
activity, system idle 100%, file systems unmountable) when copying large
files on gbde fs over md. When i restart system, reattach and fsck the
gbde fs, all latest modifications are lost (lot of files in lost+found).

As this is my first try on gbde, i have not tested against a real
disk partition, so maybe this is a md(4) problem. 

I was running -CURRENT from around 01 October, i have upgraded to
yesterday -CURRENT and still the same problem.

cp -Rp /a_dir/w_sub_dirs to gbde vnode on SmartMedia Card locks system

[Donald Creel]

This has been reproducible for the last few weeks. System will crash if
I am strictly from ttyv(n) or using KDE3.x and drag and drop.
By crash, I mean that kb and mouse will lock up if in XFree86, and if
only at virtual terminal, eventually all 8 will quit responding to commands,
though the commands make it to the display, passwords are in cleartext if
I enter them at the login prompt.
I have tried near the beginning of the event to kill gbde related
processes from the second ttyv(n), which does seem to extend the time
before the system has to be powered.

However, if I just copy a bunch of files from a single directory, all is ok.
At this time I have not tried to copy a directory containing only files.

2. Create virtual device that points to img file.
mdconfig -a -t vnode -u 9 -f /mnt/dcim/efs.img

3. Attach virtual device to efs.img
