My kernel konfig: http://morpheus.mediahosting.hu/server1.html

i got similar issues with efi_32 when compiling with grsec patch, i didn't bother testing if the vanilla kernel would do the same, i just disabled efi_32 and the kernel compiled fine

fixed in test28. have you actually got a box that boots with EFI? 'cos i had to rewrite this code quite heavily years ago and found noone who could test it for me ever since (especially when mixed with PAE).

well, my new pc can probably boot with efi, but i'm only running linux on my old pc with a 1ghz celeron cpu, so it obviously doesn't support efi

Sorry, I haven't got EFI compatible box, I turned on this option for test. I tried test28 and test30 patch too, but a new error has occured.

I tried the new patch (grsecurity-2.1.11-2.6.24.2-200802192340.patch), and it's work fine. Many thx for help !
