For what it's worth, I managed to test the other day with two separate T41 machines (one with help from a local FreeBSD user) on -CURRENT, and the machine I was testing on did *not* demonstrate the CD-RW/DVD related crash. This was based on a simple hard drive swap with my own T40 which doesn't have any problems running -CURRENT: empiric:~ % uname -a FreeBSD empiric.dek.spc.org 5.2-CURRENT FreeBSD 5.2-CURRENT #1: Tue Jul 6 23:17:47 BST 2004 [email protected]:/usr/src/sys/i386/compile/EMPIRIC i386 Further inspection revealed that the part numbers, and indeed firmware revisions, of the modules were IDENTICAL... The BIOS and ACPI embedded controller versions were also identical. At the moment I have very little to go on and don't have kernel crash dumps to work from. > 2) Modem.

The Linux driver is actually just a wrapper around the software modem code which is linked using obfuscated ELF symbols. I haven't had time to sit down and attempt to port, but I believe the porting process should be very similar to that used for the Lucent ltmdm port. Most 'standard' PCMCIA modems with their own microcontrollers should work. > 3) What is the proper device name for a pccard moden inserted into slot1? Quite often these are numbered as sio3 upwards in my experience, but this isn't guaranteed. The last time I used such a card, I had to rebuild sio as a module with a patch from Warner which supplied a pccard attachment in addition to the ISA one so that the card would probe and attach (exca, cardbus, and pccard were also built as modules).
