The K2 is used in a legacy product after all, and the more senior colleagues were quite concerned about making such a major change due to various hacks that might fall apart along the way. Therefore, we will go the CIP path by staying with the last SLTS kernel with full highmem support. Therefore, we would be very glad if this is the case for at least the next SLTS kernel, supposedly to be released in 2027, as we should then be able (despite barely) to meet our projected EOL of 2037. Thank you for your help so far! Kind regards, Stefan
