Re: kernel oops and panic in acpi_atomic_read under 2.6.39.3. calltrace included

[rick]

Hi Huang,

I've been running for a while now with this new patch.  I have not gotten
any panic output though.  This is the only output I have from GHES:

[22256.616069] GHES: gar accessed: 0, 0xbf7b9370
[102115.873369] GHES: gar accessed: 0, 0xbf7b9370

[686744.665292] GHES: gar accessed: 0, 0xbf7b9370

Do you think changing from 5620-5670 cpus changed the behavior?

Thanks,
Rick
