slb_flush_and_rebolt panic trace in 2.6.12-rc2-mm3

[R Sharada]

Hello,
	I was trying to boot the latest kernel version, 2.6.12-rc2-mm3 on a 
p630 box, and found the kernel throwing up this call trace after boot. It does
come down to the login prompt, but keeps throwing out the below call trace when
you attempt to do any operations on the box.

Anyone else seen this problem on this kernel version? 2.6.12-rc2-mm1 was working
fine for me on the same box. I use the default pSeries_defconfig config options.

Thanks and Regards,
