Retested this compile error with todays 2.6.23-rc1+git, still the same.

Hmm. Just make works, make bootimage does not. I debugged this further today and I can not see how it can work.
The link command in question is ld -static -uvsprintf -T arch/alpha/boot/bootloader.lds arch/alpha/boot/head.o arch/alpha/boot/main.o -o arch/alpha/boot/bootloader and it still tells arch/alpha/boot/bootloader.lds:25: undefined symbol `srm_printk' referenced in expression
arch/alpha/boot/bootloader.lds contains a single related line referring to srm_printk: printk = srm_printk; This only seems to define an alias to srm_printk so not important (and unused)?
nm arch/alpha/boot/head.o outputs 0000000000000000 T __start 0000000000000108 T halt 0000000000000110 T move_stack U start_kernel 0000000000000060 T switch_to_osf_pal 0000000000000100 T tbi 0000000000000020 T wrent 0000000000000040 T wrkg
so no mention of srm_printk.
nm arch/alpha/boot/main.o outputs U _end U callback_close U callback_getenv U callback_open U callback_read 0000000000000000 G hwrpb 0000000000000000 T pal_init 0000000000000000 b pcb_va U srm_printk 0000000000000130 T start_kernel U strcpy U switch_to_osf_pal
and the U srm_printk is breaking things. main.c actually uses srm_printk inside so it really needs to link one in. I do not see where that srm_printk could come from? The only implementation seems to be in arch/alpha/lib/srm_printk.c that goes into arch/alpha/lib/lib.a.. maybe this is forgotten?
arch/alpha/boot/Makefile contains different link rules for bootloader vs bootpheader and bootpzheader - the others also have $(LIBS_Y). However, as trial and error showed, adding $(LIBS_Y) to get lib/lib.a does not work - I got new unresolved symbols (__kmalloc or some other malloc variant).
So, can anyone guide me further - where should srm_printk come from in bootloader image?
