something more like "There's no hardware responding at this IRQ.

don't give elementary advise in device driver messages anyway. Be
that as it may, the problem with it printing all the time should be

which caused incomplete snapshots to be taken. When background
fsck would run on these snapshots, the result would be files
being incorrectly released which would subsequently panic the
kernel with ``handle_workitem_freefile: inodedep survived'',
``handle_written_inodeblock: live inodedep'', and
``handle_workitem_remove: lost inodedep'' errors.
and the reference to db_regs is *extern* from alpha/include/db_machdep.h
(put it in alpha/alpha/machdep.c)- this avoids the problems we've had
about different 'common' sizes prohibiting the kernel from linking.
One to notify the system that the MTU for VLAN can be 1500 so the vlan
will automatically be configured with a 1500 MTU the other is to ignore
the error case if the received frame is to long.
The frame size notification came from code in the SIS driver, and
the support for long frames derived from the NetBSD Tulip driver.

to reduce core temperature).

add them back).

different).

variables for these limits that are calibrated in the MD startup code
somehow.
NULL rather than curproc. Without this, if we trap early before
curthread is set, we recursively panic.
- In an SMP kernel, if we trap before curthread is set, then trap is going
to recursively panic trying to bump td->td_md.md_kernnest. The trap is
fatal anyways, so to make debugging easier just call printtrap() to
dump the trap info to the console and then halt.
involving file removal or file update were not always being fully
committed to disk. The result was lost files or corrupted file data.
This change ensures that the filesystem is properly synced to disk
before the filesystem is down-graded.
This delta also fixes a long standing bug in which a file open for
reading has been unlinked. When the last open reference to the file
is closed, the inode is reclaimed by the filesystem. Previously,
if the filesystem had been down-graded to read-only, the inode could
not be reclaimed, and thus was lost and had to be later recovered
by fsck. With this change, such files are found at the time of the
down-grade. Normally they will result in the filesystem down-grade
failing with `device busy'. If a forcible down-grade is done, then
the affected files will be revoked causing the inode to be released
and the open file descriptors to begin failing on attempts to read.

Introduce a new poll op "POLLINIGNEOF" that can be used to ignore
EOF on a fifo, POLLIN/POLLRDNORM is converted to POLLINIGNEOF within

This should allow one to view a fifo pretty much as a data source
rather than worry about connections coming and going.

MFC at: earliest convenience
detect 3.3V cards for the 6710 and another method for the 6722. This
latter method is also how the 6729/6730 is supposed to detect 3.3V
cards. This method works great on my Fujitsu Stylistic 500. Sadly,
it appears that not all laptop makers are as detail oriented as the
folks that made the Stylistic. IBM Thinkpad 701C and AST Asentia 810N
both hang hard when the 6729 method is used, but at least the thinkpad
works when the 6710 method is used. The failure mode appears to be any
access to the memory that we've mapped the CIS in causes the machine to
hang until you eject the card. The Thinkpad, at least, works with this
change, and it doesn't break my Stylistic.
