I've been using Linux bridging (from Lennert Buytenhek) on
a 2.2.16 kernel for a while now and it seems to work fine.
Anybody know of any way I could implement

Thanks in advance for any help.

Allan,
my graphic card is a matrox 1- video card is a haupauge/model618pci , no AGP
or DRM. The output of ver_linux + lsmod below. There has to be significant
change from test13pre7 to prerelease ff. There is an immediate standstill,
nothing in /var/log/messages or /var/log/warn.
kind regards

Ok, lets just fix filemap_fdatasync. We can tackle the msync/fsync
interaction with screwed up FS writepages later, since all of the existing
writepage funcs are safe. The problems I see with filemap_fdatasync when
writepage returns 1:
The page dirty bit is not reset.
the page is never unlocked

Precisely. Users of embedded devices don't expect to have to treat the
Hello,
I have just been bit by this bug(hardware?) while using the
2.4.0-prerelease kernel. The fix has been included in recent
2.2.19pre kernels and I was wondering if there are plans to
include it in 2.4. It requires a reboot to repair so it is

Also, is it a confirmed ha

Clueless ? Hardly. Every other appliance in the home you turn it off and it
goes off. You turn

1. setup the power switch so it doesn't actually turn things off (it

2. run from read-only media almost exclusivly so that power event's don't
