It seems that there is two problems on U2.(I know hme(4) issue too.) 1. esp(4) works well but its sync. rate is terribly slow(6.25MHz). 2. I have an annoying problems on ssh connection. From time to time, the connection attempt is failed with "key_verify failed for server_host_key". Further investigation shows there is an issue in bn library of OpenSSL. Builing OpenSSL without any optimization seems to fix the issue. But I don't think this is a bug of compiler since the same optimized code works well on AXe. Is it possible one code works on UltraSparc-IIi processor and the same code doesn't work on UltraSparc-II processor?(I vaguely guess UltraSparc-II processor has more cache memory(2MB)) Regards, Pyun YongHyeon -- Pyun YongHyeon
