config kernel mumble mumble
line has been obsoleted and removed and with it went all knowledge of
devices on the part of config.
You can still configure a root device (which is used if you give
the "-r" flag) but now with an option:
options ROOTDEVNAME=\"da0s2e\"
The string is parsed by the same code as at the "boot -a" prompt.
At the same time, make the "boot -a" prompt both more able and more
informative.
ALPHA/PC98 people: You will have to adapt a few simple changes
(defining rootdev and dumpdev somewhere else) before config works
for you again, sorry, but it's all in the name of progress.
interrupt configuration reported. (I just discovered my vga card is
being configured for irq 5... :-) This is just reporting. The vga_isa
driver does the real work using the isa compat mappings.
I'm not too happy about the result either, but at least it has less
chance of backfiring.
This particular feature could be called "a mess" without offending
anybody.
If the client requests that the error recovery code retry a selection
timeout, it will be retried after half a second. The delay is to give the
device time to recover.
For most of these drivers, I only added selection timeout retries where
they were also retrying unit attention type errors. The sa(4) driver calls
saerror() in a number of places, but most of them don't request retrying
unit attentions.
Also, bump the default minimum CD changer timeout from 2 to 5 seconds and
the maximum timeout from 10 to 15 seconds. Some Pioneer changers seem to
have trouble with the shorter timeout.

and ISA DMA channels (ie: on most PCI systems, they are not.. they are
on the ISA side of the PCI-ISA bridge and could be duplicated if there
were multiple PCI-ISA bridges, say in a laptop docking station), while
the APIC resources would be global on SMP systems.
Also, revert a previous change, change some printfs back to panics.
