-current kernels have wrong magic when net-booting?



Hi,

while attempting to boot -current kernels on a few Macs (a Quadra 650 and
two 700) I found that they would boot from harddrive, but not when
net-booted. Here, the kernel was rejected because of a wrong magic (boot
log attached). I tried a pared-down kernel config of 9.99.82 sources, same
result.

Older kernels (5.99.62, 7.99.something) were recognized.

Has anything on the NetBSD side changed here recently, or are the kernels
just too big now? Does anybody else net-boot?

Cheerio,
Hauke
