I rebuilt the kernel(same kernel, 2.4.22), to upgrade
to include SCSI support for a CD-R I got.
Now the new device is recognized, but, I lost ppp

Although I included ppp support in menuconfig, I get as arror
Couldn't set tty to PPP discipline: Invalid argument
In google I found a hint that the problem may be
PPP support for asynch serial ports
ppp_async.o and ppp_synctty.o

But is this some menu in menuconfig I missed?
Don't see any such thing there!

Also, another thing with the rebuilt kernel,although the cd-r device is recognized, when I try to burn a CD, K3B says no disk found, even though there is a blank 700M CD in there. Any ideas?
