Hi All,

I'm using kernel 2.6.24 and when it comes to line 826 on the file
arch/ppc/kernel/head_4xx.S it gives a TLB Miss.

arch/ppc/kernel/head_4xx.S
823 start_here:
824
825         /* ptr to current */
826         lis    r2,init_task@h
827         ori    r2,r2,init_task@l

I am just curious: how did you find that you have TLB miss on that
line?  Is it an Instruction TLB miss or a Data TLB miss?

Can you paste a dump of your registers (in XMD, rrd and srrd)?

I was having TLB misses awhile back due to some other problems, but
never had any on that line though.
