rEFInd hangs whenever any fs driver is present on T100TA tablet

[Gustaf Johansson]

Hi,

I have built rEFInd for ia32 from src using gnu_efi and when it is installed to the EFI partition it hangs with a black screen whenever a driver (any driver at all) is present in the drivers_ia32 directory.
Booting from a removeable medium (USB) works with the same build though.

I have also tested the 0.10.1 build which works as expected.
I have also tested with my build but drivers from 0.10.1 and that also works as expected so obviously it is something with the drivers.

I can do some debugging of this if given the pointers to what to look for, but for now I can use the pre-built drivers (as I only want to modify the binary at this point).

I've seen something similar on a 32-bit Mac Mini I own, but not under a 32-bit VirtualBox system. I banged my head against the wall for many hours trying to debug it, with little progress. It looked as if a function was being called in the middle, which of course meant things went downhill fast. There's a big fat comment about that in fsw_efi_read_block() in fsw_efi.c. If you can identify the cause, the help would be most welcome! If not, I'm sure I'll try again eventually. In the meantime, I recommend using the binaries built via TianoCore, which seem to work fine. (Mac users normally install my binary build, which provides TianoCore-built binaries, and since I only ran into this on a 32-bit Mac, using the TianoCore build seemed like an acceptable workaround.)
