私はもっともカーネル立ち上げれます。しかし「root file system type:
ffs」を刷ったあと、エラー送ります。これはブートとデーバグはEverex
Associate A-10と16MBのRAM.私のconfigフィルは「HPCMIPS_FLUSHCACHE_XXX」
を持っています。

I was able to boot the latest kernel. However, after printing "root
file system type: ffs", an error happened. Here is the boot and
debugging on my Everex Associate A-10 with 16M of memory. I've set
HPCMIPS_FLUSHCACHE_XXX in my config file.
# Commentary below is in English.
Briefly, it looks like the memory for the arg to the rtc interrupt
routine is in allocated from kernel memory, but for some reason the
tlb entry for allocated kernel memory isn't present. I don't know how
to get a dump of the tlb entries from this version of ddb, so I can't
report what is in there. Ideas on how to proceed from here?
Thank you very much for any assistance.
