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.
that big a deal just yet and isn't worth a whole line on the boot screen.
This could change later in the face of multi-ISA-bus (eg: laptop docking
stations with two independent ISA busses) and SMP/APIC systems. The Alpha
already has multiple interrupt destinations to deal with.
development that leads to lots of crashes during boot.
I have made a 'reinstall' target (like in ports, and reinstall.debug)
This is most useful if you want to keep /kernel.old as a known bootable
kernel. If you test a new kernel and have to reboot for a fix, a
'make reinstall' will install the new kernel over the top of the old
non-viable one, leaving the old one untouched. This is mainly meant
for development, not general users.
Change haveseen_isadev() to something a little easier to emulate.
Store the device_t for the wrapper in isa_device.
Implement a replacement for haveseen_isadev - namely haveseen_ioport()
which takes a port size as an extra argument for a proper range check.
This (haveseen_ioport()) has not been tested, but I think it'll work.
new isa drivers with sensitive flags. If the resource_find() code
is meant to "find" the wildcard sensitive flag for a driver even though
a unit is supplied, this can be simplified.
Restore 0x710110b9 ("AcerLabs M15x3 Power Management Unit") - but only
if NALPM == 0.
Restore 0x00051166 ("Ross (?) host to PCI bridge") so that
fixbushigh_Ross() gets called.
Delete generic_pci_bridge(), it's been replaced by other mechanisms (see
the isab and pcib match/probes and the pci_bridge_type() function)
o fix DDB support
- include "opt_ddb.h"
- fix Debugger() arg
pointed out by bde
o back out pvc shadow interface support
- it is currently not used
- to make it easier to merge another implementation
o misc minor cleanup
