I only commented out the "brk = NULL;" line enclosed in the "#if defined(__alpha__)" block. But I can recheck everything. I must say, the machine is old and super slow, I untarred a kernel and applied the for-next patches then your alpha series on top of it. Cloning via git would take a day or two based on my experience with haproxy which is hundreds of times smaller... > How does it behave in QEMU for you?

For an unknown reason the console stopped responding yesterday, and now it only speaks but I cannot enter anything. I suspect a voltage issue (same with two adapters). Anyway it was the default config from the 6.12 debian 13 kernel apparently. Will report back when I figure out this console issue (I'm still having machines with real serial ports anyway). Willy
