[Qemu-devel] [Bug 1252270] Re: installing NT4 on MIPS Magnum/Jazz asserts

[Andreas Färber]

We're about to release 2.0, so it would be more interesting to know
whether it still happens in latest qemu.git.

And since this seems to depend on .iso and nvram.bin files that we don't
have available for reproducing, some tracing on your part might help
narrow down whether this is caused by a bug in MIPS-specific or generic
SCSI code and what exactly it's been trying to do at the point of
assertion. Running it in gdb to get a backtrace on SIGABRT would be a
start. --enable-trace-backend= and -trace would be further options to
investigate.

Title:
  installing NT4 on MIPS Magnum/Jazz asserts

Status in QEMU:
  New

Bug description:
  While installing NT4 on MIPS Magnum (Jazz), when the NT Installer
  tries to format the harddisk, QEmu 1.6.1 crashes with an assertion:

  qemu-system-mips64el: g364: invalid read at [0000000000102000]
  qemu-system-mips64el: hw/scsi/scsi-bus.c:1577: scsi_req_data: Assertion 
`req->cmd.mode != SCSI_XFER_NONE' failed.
  ./nt4mips.sh: line 3: 20336 Aborted                 (core dumped) 
./qemu-system-mips64el --machine magnum -m 64 -net nic -net user -hda nt4.dsk 
-cdrom NTWKS40D.ISO -global ds1225y.filename=nvram.bin -global 
ds1225y.size=16384

  This assertion also occurred with the stock Ubuntu version of QEmu
  (1.5.0 (Debian 1.5.0+dfsg-3ubuntu5)) which I tried before.

  Note that to even get this far, you need the patch mentioned in
  BUG1245924, otherwise QEmu 1.6.1 won't even start/boot at all

  NT4 installation guide I'm following:
