dialog(1) is run without arguments and works as expected. Therefore,
it should be part of the manual as well.
Note: dialog(1) has not been updated for many years and is not actively
maintained at the moment.

Because slave PICs send all interrupts to their CPU 0 output line (which
is routed to a pin on the master PIC), changes to per-CPU register banks
like EOI on the slave PIC must be accessed for CPU 0, instead of the
CPU actually processing the interrupt.

There are special cases where tty_rel_free() can be called twice in a
row, namely when closing and revoking the TTY at the same moment. Only
call destroy_dev_sched_cb() once.

the context of the process that reduced the effective count. Previously
all truncation as a result of unlink happened in the softdep flush
thread. This had the effect of being impossible to rate limit properly
with the journal code. Now the process issuing unlinks is suspended
when the journal files. This has a side-effect of improving rm
performance by allowing more concurrent work.
- Handle two cases in inactive, one for effnlink == 0 and another when
nlink finally reaches 0.
- Eliminate the SPACECOUNTED related code since the truncation is no
longer delayed.

directory truncation to proceed before the link has been cleared. This
is accomplished by detecting a directory with no . or .. links and
clearing the named directory entry in the parent.
- Add a new function ino_remref() which handles the details of removing
a reference to an inode as a result of a lost directory. There were
some minor errors in various subcases of this routine.

numbers. This change adds a new function alloc_unr_specific() which
returns the requested unit number if it is free. If the number is
already allocated or out of the range, -1 is returned.
Update alloc_unr(9) manual page accordingly and add a MLINK for
alloc_unr_specific(9).

apart from generally doing the wrong thing can lead to a panic when a
CPU is told to IPI itself (which sun4u doesn't support).

is ordered by page index. This greatly simplifies the implementation,
since we no longer need to mark the pages with VPO_CLEANCHK to denote
the progress. It is enough to remember the current position by index
before dropping the object lock.
Remove VPO_CLEANCHK and VM_PAGER_IGNORE_CLEANCHK as unused.

refuse to attach rather than panic with a division by zero (in one of
many places) down stream.

large number of packets queued to a crashing process.
In a specific case you may get 2 ABORT's back (from
say two packets in flight). If the aborts happened to
be processed at the same time its possible to have
one free the association while the other is trying
to report all the outbound packets. When this occured
it could lead to a crash.

FreeBSD. SIFTR logs a range of statistics on active TCP connections to a log
file, providing the ability to make highly granular measurements of TCP
connection state. The tool is aimed at system administrators, developers and
researchers alike. Please take it for a spin and test it out - the man page
should have all the information required to get you going.
Many thanks go to the Cisco University Research Program Fund at Community

at the Centre for Advanced Internet Architectures, Swinburne University of
Technology is greatly appreciated.
