In FreeBSD 7.1 -32bit, the PAE kernel configuration file is included with the distribution, one doesn't need to create it. Steps that I followed- cd /usr/src/sys/i386/conf config PAE cd ../compile/PAE make cleandepend && make depend make make install reboot Systems works perfectly with 16GB RAM(This means PAE is working in the guest.) * With 24GB & 32GB memory, system hangs & gives error- Panic : Page fault error. * With 64GB of RAM, the system hangs & gives error- MONITOR PANIC: vcpu-0:DoubleFault @ 0x4020:0xb91d8 (0xff0,0x1064) (0xb6cb8, 0xb9130) FreeBSD 7.1 - 64bit There are no issues uptil 24GB RAM. * With 32GB RAM, system hangs & gives error- Panic : Page fault error. * With 64GB of RAM, the system hangs & gives error- MONITOR PANIC: vcpu-0:VMM64 DoubleFault src=MONITOR @ rip=0xfffffffffc24e530 rsp=0xfffffffffc001000 regs=0xfffffffffc048f40 (0xfffffffffc24e9f1,0xfffffffffc24e530 My query is- (1) 64GB works fine if PAE is enabled in 32bit FBSD 7.1 32bit? (2) Am I making any mistake in executing steps. (3) The reason behind Panic: Page fault (4) The reason behinf Memory Panic (5) Is this a OS related issue. Please let me know the solution for the above issue. Thanks in advance. Vishwas >How-To-Repeat: If I change the RAM size to 16GB, both of the dead systems are UP & work very well. Ofcourse, it takes a large "UP time". (may be 10-15 mins) If one changes the system ram to 64GB, the issue can be reproduced. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
