Odd problem with HPE smart array and sanboot

[p4rancesc0]

Hi everybody, still so sorry for the triple posting.

I did some more testing:

If the ipxe script contains only:
console
and then execute manually
sanboot

everything get stuck

But if I press control + B, enter the iPXE console, and issue the command:
sanboot
everything works like charm...


So, I guess which is the difference between the CTRL+B console and the console instance created with the script.

I did some debugging...

This is code line where everything get stuck:

PHP Code:

__asm__ __volatile__ ( REAL_CODE ( "pushw %%es\n\t"
                                           "pushl %%ebx\n\t"
                                           "popw %%bx\n\t"
                                           "popw %%es\n\t"
                                           "stc\n\t"
                                           "sti\n\t"
                                           "int $0x13\n\t"
                                           "sti\n\t" /* BIOS bugs */
                                           "jc 1f\n\t"
                                           "xorw %%ax, %%ax\n\t"
                                           "\n1:\n\t"
                                           "popw %%es\n\t" )
                               : "=a" ( status ), "=b" ( discard_b ),
                                 "=c" ( discard_c ), "=d" ( discard_d )
                               : "a" ( 0x0201 ), "b" ( *address ),
                                 "c" ( 1 ), "d" ( drive ) ); 


it's inside :

src/arch/x86/interface/pcbios/int13.c

the function is:

static int int13_load_mbr ( unsigned int drive, struct segoff *address )
