Re: [Xen-devel] XenOProfile may have the conflict with SATA AHCI mode.
I once thought maybe the problem is caused by the failure of loading AHCI driver. So I added --preload=AHCI when building ramdisk for Xen after XenOProfiling is enabled.
However, Xen still booted into kernel panic with weird mount errors.I used some patch for XenOProfile nmi_int.c to make it work on Intel core 2 based processors. I notice Xen also updated nmi_int.c a couple of days ago to make XenOProfile recognize Intel core 2 based processors. I hope the problem is not caused by the updates of nmi_int.c.
BTW, The BIOS is already flashed to the latest I could get. Liang----- Original Message ----- From: "Ian Pratt" <Ian.Pratt@xxxxxxxxxxxx> To: "Liang Yang" <multisyncfe991@xxxxxxxxxxx>; <xen-devel@xxxxxxxxxxxxxxxxxxx>

I notice this issue recently when I'm using XenOProfile with the
Xen-unstable repository. I have several SATA disks to hose several
domains. For the performance purpose, I want to use the on-board AHCI mode so each SATA disk has its own data transfer channel. However, I found XenOProfile has some conflict with AHCI mode as Xen will boot into kernel panic with weird mount errors after XenOProfile is enabled. The
is gone when I set SATA mode to compatible in BIOS (i.g. IDE emulation mode).
XenOProfile is the only thing that uses NMIs, but I've no idea why that would interfere with the SATA controller. If you were seing the issue round the other way I'd suspect something dodgy with the BIOS'es SMM mode. Might still be worth checking for a BIOS upgrade.
