Thanks, I can see from cpuid_info0.cpi_extd[6].cp_ecx[15:12] where the
associativity was
derived from (0xa), so we were assuming an AMD style cache description
(amd_l2cacheinfo()).
cpuid_info.cpi_std[2] is filled with 0x20 descriptors...for which we
don't have an entry in our
tables. If the appropriate CPUID reference says we should be using
function 2, then that's probably
the problem.
I've filed:
6580117 panic: assertion failed: ISP2(CPUSETSIZE()) on VIA Esther
based system
for this.
Thanks,
-Eric
