Idle priority is not even time-share, so if system is busy in any way,
those events may never be executed. Since in some cases system waits
for events processed by that thread, that may cause deadlocks.

it manually, using "/etc/rc.d/netif restart".

Previously only TX IP checksum offloading was disabled but it's
reported that TX checksum offloading for UDP datagrams with IP
options also generates corrupted frames. Reporter's controller is
RTL8168CP but I guess RTL8168C also have the same issue since it
shall share the same core.

BULK or CONTROL transfers and poll the endpoint(s) for 1 millisecond
at 125us rate interval, before going into slow, 10ms, NAK polling mode
again. This has the effect that typical ping-ping protocols respond
quicker when initiated from the USB host.

The last obstacle to switching PowerPC entirely to vt is that the Playstation 3
framebuffer driver needs to be ported over. This only applies for powerpc64,
however.
on my G4 iBook by more than half. Still 10% slower than syscons, but that's
much better than a factor of 2.
The slowness had to do with pathological write performance on 8-bit
framebuffers, which are almost universally used on Open Firmware systems.
Writing 1 byte at a time, potentially nonconsecutively, resulted in many
extra PCI write cycles. This patch, in the common case where it's writing
one or several characters in an 8x8 font, gangs the writes together into
a set of 32-bit writes. This is a port of r143830 to vt(4).
The EFI framebuffer is also extremely slow, probably for the same reason,
and the same patch will likely help there.
