The NAND bad block code is throwing an error at startup of 'nand_bbt: Out of memory' for large block NAND flash (block size of 128K). The vmalloc() call is trying to allocate 135,168 bytes. CONFIG_SYS_MALLOC_LEN is (0x10000 + 128*1024).

Bumping CONFIG_SYS_MALLOC_LEN to (0x20000 + 128*1024) wasn't sufficient, however (0x40000 + 128*1024) was.

Any recommendations what this should be adjusted to? The system has 256MB of RAM and a single 512MB NAND.

I would use something like 1MB. This will give you enough for other malloc- intensive things like UBIFS as well.
