No, it's OK. The call to schedule_timeout() will take care of that:
* You can set the task state as follows -
*
* %TASK_UNINTERRUPTIBLE - at least @timeout jiffies are guaranteed to
* pass before the routine returns. The routine will return 0
*
* %TASK_INTERRUPTIBLE - the routine may return early if a signal is
* delivered to the current task. In this case the remaining time
* in jiffies will be returned, or 0 if the timer expired in time
*
* The current task state is guaranteed to be TASK_RUNNING when this
* routine returns.

Indeed.

I've been using "lilo -R" a lot too, but not the reboot on panic.

Yes. I've re-done it slightly differently, though, to better preserve
the unpatched kernel's behavior when all 10 retries fail.
Thanks again,
