do_page_fault question

do_page_fault question

[Paul W]

I brought up the 2.2.14 kernel (from Monta Vista) on an 860.
The only changes I made had to do with my board's uniqueness
in the serial and ethernet I/O. The kernel boots fine wit
an nfs root file system (one from Monta Vista) or an initrd
disk image. But once I get to init() I get swamped by messages
from do_page_fault() (here are the first 5):

address: 30025e30 nip:c000a7c8 code: 000048a6 data
address: 30025e30 nip:c000a7c8 code: 82000000 write I/O data
address: 10016fe8 nip:c000a7c8 code: 000048a6 data
address: 10016fe8 nip:c000a7c8 code: 82000000 write I/O data
address: 30010200 nip:30010200 code: 4000d032 604 tlb&htab miss instr

I took out the printk that's doing this and found that things
are working (shell comes up, I can enter commands and do things).
Any suggestions on how to fix this correctly would be appreciated.

Thanks,
Paul Westenkirchner

I see that in later versions of the kernel the printk() in do_page_fault() is gone - must have been a debug statement that got left in the source I picked up.
