Dear Debian-Mips Developers:
I'd like to ask a question about use of the 'mem=' kernel parameter. When booting without this parameter, the kernel automatically detects the amount of memory as 989020 kB. If a kernel parameter is added to specify 'mem=989020k' a TLB Miss error is encountered. Do you all have guidance about how the memory parameter can be specified without causing the error? Since the mem= parameter was set to an identical value as the memory reported by meminfo in the /proc filesystem, use of this kernel parameter should be OK. This behavior has been observed on both the BCM1250/1480 platforms when running Debian linux. The 2.6.17-2 kernel is used with the system. Thanks, Gary -- Gary A.
