As a result, I found a few more issues in the current c-r4k.c file. In "r4k_blash_scache_page_setup", "r4k_blash_scache_page_indexed_setup", "r4k_blash_scache_setup", and "local_r4k_flush_icache_range", there are similar checks on "scache_size" that need to be removed for my platform. I was still getting the odd "seg fault" during boots and this seems to have fixed it. One question I have regarding this is, does anyone have a tool that I can run to test this cache code and really exercise the cache? The problems are so random and infrequent that it's difficult to know if the problem is gone or just more hidden. Ralf, I imagine since you are the one with intimate knowledge of this code that you may have developed a tool or have used a tool to really test this code. -- View this message in context: http://www.nabble.com/O2-RM7000-Issues-tf4008392.html#a12905373 Sent from the linux-mips main mailing list archive at Nabble.com.
