Hi all:
Can anyone run gem5 full system simulating alpha with 8GB memory?
I am trying to run it with 8GB, but I get the following error:
warn: Prefetch instrutions is Alpha do not do anything
warn: Prefetch instrutions is Alpha do not do anything
gem5.debug: build/ALPHA_FS/dev/ide_disk.cc:462: void
IdeDisk::doDmaDataWrite(): Assertion `cmdBytesLeft <= (131072)' failed.
and print the following panic when I use gem5.fast:
warn: Prefetch instructions in Alpha do not do anything
warn: Prefetch instructions in Alpha do not do anything
panic: attempt to execute unknown instruction (inst 0x10a332030, opcode 0x2)
The value of the cmdBytesLeft which caused the assertion is: 4294713344
This problem are posted by Kaicheng Zhang but without any reply:

I am also like Zhang using a linux 2.6.22 kernel, and
alphaev67-unknown-linux-gnu- cross
compilers downloaded from gem5.org. Using the kernel and disk image gem5.org
will get the same error. The simulator worked in memory size of 4GB.
The terminal output stopped at:
