Very curious that the assembler is not getting disassembled here. it seems to be in drivers/hid/hid-core.c::implement(), the line x = get_unaligned_le64(report); and signal 4 seems "SIGILL". So I guess it is emitting an instruction my PPC970 cannot handle. :( -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

That's strange. The help for that entry says: Cause the compiler to optimize for the PPE of the Cell Broadband Engine. This will make the code run considerably faster on Cell but somewhat slower on other machines. This option only changes the scheduling of instructions, not the selection of instructions itself, so the resulting kernel will keep running on all other machines. When building a kernel that is supposed to run only on Cell, you should also select the POWER4_ONLY option. I'll disable it anyway. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
