Thanks a lot for looking into this.

The stack adresses of the word containing trap+563 and the one containing
vfs_busy+226 are 256 bytes apart, but sizeof(struct trapframe) is 208.
Actually, the word containing vfs_busy+226 could be the rip of the trapframe,
right?
So I think I'll have to guess where the structure actually is. What are typical
values of tf_trapno and tf_err (or any other structure members) I can expect
to find?

No. They were running some quota commands at taht point.

Great, thanks.
