Subject: Re: 2.6.21-rc3-mm2 (oops in move_freepages)
FYI, I'm seeing the following oops with 2.6.21-rc3-mm1 (and -mm2)
on the HP rx2600 and an Intel Tiger (both ia64 boxes).
I haven't investigated this other than to determine that it
does not occur with 2.6.21-rc3 or 2.6.20-rc3-mm1, and the
instruction at move_freepages+0x10 is a load of the value
pointed to by the third argument (end_page).
Linux version 2.6.21-rc3-mm1 (helgaas@...er) (gcc version 4.0.3 (Debian 4.0.3-1)) #2 SMP Tue Mar 13 16:16:22 MST 2007
