[Qemu-devel] SPARC kernel oops with logging |

Hi,
When I run qemu-system-sparc with -d in_asm,out_asm the Linux kernel
crashes when it tries to initialize the hard drive. The same hard
drive image boots perfectly if I do not include the logging options.
The error messages that I receive are shown below. I'm wondering if
the logging is causing some type of acknowledgment to be delayed and
this is causing a SCSI operation to timeout. I've also attached log
of the complete console output in case anyone would find it useful.
If anyone has ideas about the cause or a possible solution please let
me know.
Thanks,
Gabriel
