1) Lots of complaining about the firewire interface (maybe this machine has a "Rev. 0" pcilynx chip that the 2.6.8 kernel's driver doesn't like?). After booting, I can't access any firewire devices. I need to use a firewire HD for periodic backups.
You might try disabling pcilynx support, if you are compiling your own kernel. I think all Apple's firewire controllers were OHCI compatible, but someone else should correct me if I'm wrong. I've used a firewire drive on my old 8500 with a PCI card for backup, and it has served me very well.
2) Complaints about the (lack of) serial ports - "Illegal UART type - Undefined". Is there a "clean" way of telling the kernal that there are no serial ports, e.g., a "dummy" serial port driver I can use? Can I unset CONFIG_SERIAL_CORE and CONFIG_SERIAL_PMACZILOG, or do I need them even though this machine doesn't have any serial ports?
Be careful here though - IIRC, this machine came from a time when there were still honest-to-goodness hardware modems in PCs and Macs. If this machine has an internal modem, it probably shows up as a serial port. If you want to keep that functionality, you want to keep serial port support. Check dmesg output for occurences of "ttyS"
3) I'm not sure why, but the kernel loads the MESH module, even though this machine, as far as I know, has no built-in SCSI. I do have an Adaptec (aic7xxx) PCI card installed, but it loads the aic7xxx module for that (and calls it SCSI bus 1, while MESH is SCSI bus 0). Can I leave MESH out of a kernel compiled specifically for this machine?
Should be okay.
In order to cure these problems and to have a leaner, meaner kernel, I installed the 2.6.8 kernel source deb that came on the Sarge distro CDs.
When I attempt to compile, the process exits abnormally as follows:
CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 sound/built-in.o(.init.text+0xb68): In function `dmasound_awacs_init': : undefined reference to `pmac_xpram_read' make[1]: *** [.tmp_vmlinux1] Error 1 make[1]: Leaving directory `/usr/src/kernel-source-2.6.8' make: *** [stamp-build] Error 2 g4-debian:/usr/src/kernel-source-2.6.8#
AWACS support probably hasn't been updated for this kernel version yet. Take a look at a thread from a couple of days ago about my own problems compiling a 2.6 kernel. In my case, I'm missing floppy drive support ... You can try disabling sound support for the time being.
