Some netgraph string length constants have been changed. This
|
||||
change requires the netgraph kernel modules and all netgraph
|
||||
userland components to be in sync. Especially users who require
|
||||
netgraph to boot need to make sure to have world and kernel in
|
||||
sync before rebooting.
|
||||
The statfs structure has been updated with 64-bit fields to allow
|
||||
accurate reporting of multi-terabyte filesystem sizes. You should
|
||||
build and boot a new kernel BEFORE doing a `make world' as the new
|
||||
kernel will know about binaries using the old statfs structure,
|
||||
but an old kernel will not know about the new system calls that
|
||||
support the new statfs structure. Running an old kernel after a
|
||||
`make world' will cause programs such as `df' that do a statfs
|
||||
system call to fail with a bad system call.

The i386 APIC_IO kernel option has been replaced by
|
||||
'device apic'. The ACPI module has also been temporarily
|
||||
'device apic'. The ACPI module has also been temporarily
|
||||
disabled, so ACPI must be statically compiled into your
|
||||
kernel using 'device acpi' if you wish to use the ACPI driver.
