Hello! I'm looking for an answer or solution regarding lsi's megaraid sata-150 working with >=2.6.11 kernel on x86_64. I've tried a few of those cards and have a very good experience with those on Linux kernels from 2.4.x to latests 2.6 on x86 platform. Suddenly I come into trouble on x86_64 platform with 2.6 kernels - those cards are working with about 512kbytes per second (write) - which is strange. If I boot 32bit kernel on same hardware the throput is about 50mbytes/s - which is showing that megaraid driver in >2.6.11 x86_64 kernels is not working properly with megaraid SATA-150 raid cards. Newer megaraids SATA 300-8 are working perfect on x86_64. Does anybody found same problem?
