AHCI - loops eComStation Boot on Virtual Box.

[Martin Iturbide]

Using eComStation 2.1
AHCI v1.22
Running it as host on Windows 7 x64 on VirtualBox? 4.1.10

If I switch from the IDE controller to the SATA controller the same boot virtual HDD, eComStation reboots in a loop when loading the desktop.

You can see the video here:

If I switch the virtual HDD back to IDE, everything goes back to normal.

Secondary disk and DVD-ROM works/boots fine with SATA. But it is not as reliable as IDE. Secondary HDD breaks connection and hang system.

I see the same behavior here.
Copying many files to an AHCI drive,
or running SysBench? on AHCI drive, will
make it reset Vbox.

I tried formatting the AHCI drive as either JFS or HPFS.

The reset actually only happens with JFS - with HPFS it
run the full copy process (20GB data), and ran all of
SysBenchs? file I/O tests.

The Disc I/O test is slow for AHCI - IDE is twice as fast
in Vbox

Could you please test with the /n switch on os2ahci.add ?

I tried the /n switch.

It still resets the guest, when running Sysbench on an AHCI attached disk.

Please remove the /n switch from OS2AHCI.ADD.
Then put a rem in front of ACPI.PSD and reboot.
OS2AHCI.ADD will load slower now, but it will load.
If you now get a trap8 instead of a reset, I know enough.
If the reset is still there we need to create a logfile from OS2AHCI
to see what happens.

Forget the above and please try the test-build I attach.
(rename os2ahci.testbuild to os2ahci.add)

This is a TEST-BUILD only for the purpose of solving this issue.
It may not be distributed and I will remove it after getting feedback.
(test-builds are not to be meant floating around)

Please let me know if this test-build solves the reset problem.
If not, we have to do the OS2AHCI-log.

This test-build may kill all bits on the system, fry the cpu and erase
the bios, so don't use it on real hardware. (Only in VBox)
:-)

OS2AHCI unofficial build -- please do not distribute

[Yoda AHCI]

The test-build seems a lot more stable for me. No resets at all;
but of a lot of test it once froze the guest. Can't be sure though,
that it was because of that driver.

Let's see what Martini says about it.

[Martin Iturbide]

Hi.

I tried today the "OS2AHCI unofficial build". I changed my VM to SATA added the first HDD iamge, second HDD and empty CD Drive.

The system boot without problems, and the second HDD seems to be reliable.
I will keep testing and let you know if I have any problem.

Thanks for looking into this problems.

Regards
Martin

I assume this issue is solved so I close this ticket.
Thanks for the feedback everybody.

Ben.
