[Xen-devel] Paging oopses

[stevegt@xxxxxxxxxxxxx]

Hi All, bad news.

After running several guests for most of the past week on the 12 Feb
build of 1.2, built with GCC 3.3.2, with 64Mb of RAM and NFS roots, I
finally got another paging oops.  The entire console log, xen and
xenolinux binaries, and System.map, are at:

        http://t7a.org/tmp/oops1-n2h54/

Let me know if there's anything else I can do.  

Steve
