Re: [Qemu-devel] Question/problems with Qemu and 64Bit Opensuse 10.2
When Qemu seems to loop I switched to monitor mode stop the emulator and gathered the output of some info operations. The info registers show that registers contain the strange values, for example: RBX=80523028 RSP=80522dc0 RIP=8025e67c Is it normal that e.g. the instruction pointer (RIP) can have such a value? Any clue where to look why this loop happens? Just as a side note: trying to print registers using p /x $r15 this show the content of R15, but using p /x $rip or p /x $rbx gives an unknown register error message.

Any clue where to look why this loop happens? They look like they were truncated to 32-bit (sign-extended negative) values. Some operations probably assume 32-bit register width.

Re: [Qemu-devel] Question/problems with Qemu and 64Bit Opensuse 10.2
Just for info: the 32 bit version of Opensuse 10.2 works and installation runs. Thus the problem seems to be something with the 64 bit emulation.
