I've dusted it off and powered it on this weekend. It still works (RTC
needs a new battery though), and the 2.6.18 kernel that I modified
many years ago still works fine with the pcnet_cs driver and my
Dynalink L10C card.

I then tried a build of master of Geert's tree, which unfortunately
doesn't fully work due to issues with the Blizzard ESP driver. I also
had similar issues with the last 2.6.2x kernel I tested in 2008(?),
after switching to the new ESP driver.
The drive is identified, set to synchronous 10 MHz mode, some
transfers are done but then it locks up. After the ESP driver runs its
recovery procedure, the bash that I run as init process exits with
code 4.

Yes, I'm from Hengelo (the Netherlands), but no, I won't be attending.
I have no idea whether there will be a Linux/m68k presence.

I don't need money, I need time :-) I looked at the changes I made to
2.6.18, most of it is pretty self contained and should still work on
5.x without too many changes, but the io.h changes are more hairy.
Also, someone once tested this on his A1200 which had a 68030 and I
believe it broke. Something about ioremap() not accepting physical
addresses that were already mapped by a fixed mapping (Zorro II
address space).

Linus knows it's alive, he just seems to wonder why it won't die ;-)
I will try to prepare a patch for the IRQ handling.

Kind regards,

Kars.
