--- Comment #2 from Andreas Schwab <schwab@linux-m68k.org> ---
The problem appears to be that devkmsg_open returns without allocating a
devkmsg_user struct if opened with O_WRONLY, which causes devkmsg_llseek to
return EBADF, even though the file is properly opened. Please report that to
the kernel devs.
