We want to put 512M of RAM in it and use the cam kernel. We duly built a 2.2-stable cam kernel configured for 512M of RAM, and installed 512M in the machine. We had to enable the BOUNCE_BUFFERS option for cam support. When we brought the machine up, it panicked on startup when probing the disk controller (aic7890/91) and gave "brkadrint" panic. We cut it back to 384M of RAM in the machine (still using the kernel built for 512M) and it booted fine. Any pointers as to what could be going wrong?
