Good afternoon kernel developers Please accept my apology for contacting you directly about this. A small group of friends, some of whom are CCed here, have come together to try and find a solution to a problem that originated with the demise of kernel 2.6:32. First some background to the issue. We are all users of Panasonic Toughbook CF-29 models (ranging from Mark 1 through to Mark 5). These Toughbooks have 2 PCMCIA card slots which are used by a variety of people for different purposes. On the CF-29 Mark 1 through to Mark 3 these slots work without problem. On the CF-29 Mark 4 and Mark 5 the last known kernel the top slot worked with was 2.6:32. This has been confirmed all all major distros by most of the small group of friends I mentioned earlier.
Thinking it was just a kernel config issue I did some comparisons between Debian 6 (Squeeze), Debian 7 (Wheezy), Ubuntu 10.04, and Ubuntu 10.10. On all machines both slots functioned as they should with Debian 6 and Ubuntu 10.04 but the top slot stopped working on Mark 4 and Mark 5 machines on the next release with the next kernel. I also tested Ubuntu 10.04 and 10.10 with the 2.6:32 and 2.6:35 kernel and both slots worked with the 2.6:32 kernel but not the 2.6:35 kernel.With my comparisons I merged the config from 2.6:32 into the current kernel for Debian 4.19 and rebuilt the kernel, no matter what configuration changes I made the top slot still doesn't function on Mark 4 and Mark 5 machines.
This issue, and its apparent start, has been confirmed on all major distro family groups. So this brings me, actually the small group of dedicated Linux users who own Panasonic Toughbook CF-29s, to contact you to ask for help in resolving this issue. I have some questions, and I realise the 2.6:32 kernel is long gone now but I'm hoping this is not a lost cause, what changes would have occurred between 2.6:32 and 2.6:33 that would have stopped the hardware working on Mark 4 and Mark 5 CF-29 Toughbooks but not Mark 1 through to Mark 3? Would it be possible to correct the problem so that the hardware on our machines works as it should. While we are not kernel devs or even programmers we are enthusiasts who love Linux and our machines and we are hoping that together with you and the kernel dev group we can fix this issue together.
I have attached various tar.gz files with ls* outputs so you can see the information we have so far. Thank you for taking the time to read this.
