Re: [Xen-ia64-devel] [PATCH 0/12]MCA handler support for Xen/ia64 TAKE 2

[Alex Williamson <alex.williamson@xxxxxx>]

Hi Kaz,

   I'm still having several problems with the MCA support patches.  I've
published my tree here:

http://free.linux.hp.com/~awilliam/xen-ia64-mca

Could you take a look and make sure I didn't break anything when
applying the patches or updating them to the latest tree?  I'm seeing
hangs during dom0 bootup.  The system has several error logs, so I
thought there might be a race.  However, if I deconfigure the 2nd CPU
(2-way Madison system), it hangs even before launching dom0.  Maybe it's
trying to retrieve an error log from the offline CPU?  On another system
I have that did boot up, I saw several of these errors:

xencomm_init_desc: could only translate 49152 of 130000 bytes
xencomm_init_desc: could only translate 49152 of 170000 bytes

Seems like we need a solution for handling larger error logs.  I think
it may also be wrong that SAL_GET/CLEAR_STATE_INFO are exposed to
non-privileged domains.  Thanks,

        Alex
