Not sure whether to post this in this bug-grub list or here, so feel free to correct me if perhaps this is in the wrong spot. I’m not sure if the issue I’m having is due to a fault in setup or a bug within GRUB.
I’m the developer of a tool called Mac Linux USB Loader, and some of my users are reporting errors with my compiled copy of GRUB. Specifically, after loading the kernel, GRUB spits out the following error message:
alloc magic is broken at 0x81493ca0: 207d007d68746170
Aborted. Press any key to exit.
The hexadecimal values vary slightly, but generally speaking this is what the error looks like. The kernel loading operation with GRUB’s linux command is followed by the initrd command to load the RAM disc, and that operation never occurs, so I know that the operation never completes.
This error never seems to occur with Ubuntu-based distributions. It also seems to occur if the kernel can’t be found - but in that case, shouldn’t the linux command fail with an error instead of something like this?
I can’t post my GRUB config at the moment, as I’m not on the machine where it is stored, but any advice that you can give me without it would be appreciated, such as under what conditions this error occurs.
Thanks,

Well, the first thing to try would be upstream HEAD to verify whether
problem is still present there.
Sorry, just realized my previous reply didn’t get posted.
The GRUB build I’m using is compiled straight from the current git repository. It might be a week or two old, but unless something really changed in the last two to three weeks I don’t think it’ll differ.
In this case you need to post to gurb-devel. Is there any way to get output to serial console?
No, I don’t think so, unless there’s some GRUB trick that I don’t know about. Once this happens GRUB crashes to a stop and I can’t do anything. I can try an older release of GRUB, like the latest stable and see if that does anything though.
