Re: [Xen-devel] file corruption!!!

I've checked in a fix. It should work fine with LVM and loop
devices again.
All seems well with that fix, with domain 0 using LVs, and exporting
them to other domains. I'll give the machine some load and see what
happens.
So, I've got the following results. The machine has an aacraid
controller, which reports no errors. My test, such as it is, is to
rebuild the 'festival' package -- simply because that's what I was
doing when I first saw corruption.
2.4.26 plus the device-mapper patch and the VFS-locking patch - stable.
Xen, 2.4.26 domain0 plus device-mapper, VFS-locking, domain 0 only -
stable.
Xen, 2.4.26 domain0 etc, and a 2.6.7-xenU guest - stable.
Xen, 2.4.26 domain0 and a 2.4.26-xenU guest - corruption in dom0, and
an oops.
The oops below happened shortly after I started the 2.4 guest, and
killed the machine. I'll run memtest86 as soon as I've got it built
with serial support and hooked into grub...
