Dan, are you saying that the bounds checking patch will solve the panic? P. (In reply to comment #2) > Dan, are you saying that the bounds checking patch will solve the panic? > P. I believe that it will, but I haven't tested it applied to the RHEL kernel. I tested the vanilla 2.6.26 kernel that contains that patch, and it booted just fine. Although, the vanilla kernel also increased the size of the array from 8 to 16 so its less likely to run off the end. Dan, I'm building x86_64 and i386 rpms with the boundary patch and that are based on build -104.el5. I will attach them to this BZ when they make it through our build system. I'll also look into increasing the size of the array -- no promises on increasing the size though as it might break kabi. P. Created attachment 314271 [details]
i686 kernel with patch
Dan, please test.
Thanks,
P.
