Ticket #4788 (closed defect: fixed)
SCSI does not work if ACPI is disabled
|Reported by:||Hawk||Owned by:|
I'm using VirtualBox to test my embedded system and I have strange problems with SCSI on Linux guest. Everything works fine on distro kernels, for example vanilla one with this config:
And when using my own kernel which I prepared for my embedded system it doesn't work. Here is config which this kernel uses:
When I configure BusLogic controller I got this in dmesg and attached virtual disks are not visible at all:
When configured as LSI Logic that appears in dmesg and modprobe hangs disallowing to load any other ide/sata/scsi module:
When configured as SATA AHCI disks are visible, but terribly slow.
It may look at as a kernel misconfiguration but the very same kernel that fails under VirtualBox works just fine on various real hardware SCSI controllers and under VMware 5.x which I digged out from my archives. I'd be thankfull for any ideas how to get it working under VirtualBox too.
