I'm having stability issues with my Amiga 1200: For several days my machine crashes at random. I'm still in the process to narrowing down the cause.
Tonight I've focused on the ACA1221ec and noticed the following error message:
contact Icomp for firmware upgrade (CPU's mask *must* be 0E30G!)

I've tried to upgrade to the latest firmware as instructed in this post: New ACA1221ec flash software, however the error still shows up.
Here's a SysInfo (4.0) screenshot:

Amiga 1200 REV 1D4 (Escom)
Amiga OS: 3.1.4 with the matching ROM. (Kickstart 46.143, Workbench 45.194)
Tools: ACA1221V1 2Beta1.lha
The Jumper on the aca1221ec is as instructed on the parking position (on one pin only), but I've also tried RomMapping.
There's also a Gayle Reset Fix, Indivision AGA MK2 and an RTC module installed.
Board seems to be good, E123C, E125C, E121C and E122C got no capacitors. I made high-res images of both sides of the mainboard, so I can report on more caps.
