Well, buying this t2k was a mistake of management, but it is kind of useful for porting my "heavily bitfielded" userspace app for big-endian's. Other choice is only PS3 or emulators in this country :-( Also this expensive Sun box is terribly slow... dunno if it is a bug of software/kernel or hardware, but it starts from latency while compiling single 100kbyte source, ending even time to make -j17 for a linux kernel source. With such price, at x86, i will see bytes popping from server like a popcorn, getting dizzy because of speed. But seems linux support of both, kind of weak, i will try to fill bugreports/patches. PS3 also had problems with WPA2 + dhcp. Recent commits with maintainers changes shows that Sony guys handling this question (not only for games) and maybe it can be fixed. Sorry for offtopic :-) Now back to main subject... I'm not sure, but maybe even 2.6.28.7, i had something similar. Kernel where hangs occuiring ,i forgot to tell, but it is visible in dmesg - 2.6.29.3. I will try meanwhile falling back to older kernels and to bisect by myself, if i will not become elder person while compiling kernel. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
