Could you try and run with opt instead of fast? You should only run fast if you've successfully run a simulation before or run something very similar to it. Having asserts and additional debugging is helpful in these situations. Clearly something has gone wrong because Linux thinks the device is 2.19TB is size. Since it is IDed incorrectly when the file system tries to read past however big the disk actually is you get the error you see.

Are you sure you're using the correct kernel? -Tony On Tue, Jul 24, 2012 at 11:04 AM, Stuart Ryan <[email protected] [3]> wrote: >> >>> Hi, I'm using gem5-stable (9073:f75ee4849c40) and having some trouble getting a FS ARM platform to boot with the arm-ubuntu-natty-headless.img (or indeed with a self made image following the instructions on the wiki - with the same error) . I have not had any problems with the busybox image (linux-arm-ael.img) nor with the android images. I use the following command to start the simulation: ./build/ARM/gem5.fast ./configs/example/fs.py --disk-image=arm-ubuntu-natty-headless.img The simulator panics with an out of bounds access to the disk: panic: access out of bounds @ cycle 195069127500 [read:build/ARM/dev/disk_image.cc, line 371] Memory Usage: 300064 KBytes The terminal shows that disk access has just started: [ 0.190100] ata1.00: ATA-7: M5 IDE Disk, , max UDMA/66 [ 0.190104] ata1.00: 4292870624 sectors, multi 0: LBA [ 0.190110] ata1.00: configured for PIO [ 0.190165] scsi 0:0:0:0: Direct-Access ATA M5 IDE Disk n/a PQ: 0 ANSI: 5 [ 0.190317] sd 0:0:0:0: [sda] 4292870624 512-byte logical blocks: (2.19 TB/1.99 TiB) [ 0.190359] sd 0:0:0:0: [sda] Write Protect is off [ 0.190363] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 [ 0.190383] sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA What steps do I need to take to get the system to play nicely with this image?
