The asm certainly misses a clobber. So, can you try adding one to this asm in vesa_store_edid: /* Note: The VBE DDC spec is different from the main VESA spec; we genuinely have to assume all registers are destroyed here. */ asm("pushw %%es; movw %2,%%es; "INT10"; popw %%es" : "+a" (ax), "+b" (bx) : "c" (cx), "D" (di) : "esi"); In particular add "edx" to the clobber list (that's the register used in my case), but the above also misses "ecx", "edi", which have to be added as in/out constraints (i.e. "+c") probably, not as clobbers. Note especially how the comment explicitely warns about assuming that all regs are destroyed, but how the asm makes no try to cater for that. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
