Xen devel - May 2012 - xen-pciback.hide bug report: parse error in current xen-4.1-stable.hg

Hello everyone,

Said Xen version running on kernel 3.3.4 x86_64.

I had put in Grub''s "module /vmlinuz.gz" line:

xen_pciback.hide=(02:10.0)(02:10.2)(etc.)

This yields an error in dmesg:

xen_pciback: Unknown parameter `2)''

I tried all sorts of variations: quoting the pci devices, prefixing
the devices with an extra 0000:, putting the thing somewhere else. But
the error keeps returning.

I am working around this by having added the hide option in a
modules.conf entry.

For further contact please be aware I am not receiving xen-devel
emails, so please include me in CC''s when more info is required.

Thank you,
Mark

Should be xen-pciback.hide (not a underscore)

Yep. Also the subject is misleading because this is a 
*Linux* dom0 kernel configuration issue, not xen-4.1-testing.hg issue.

You have compiled xen-pciback as a module, perhaps you could try to compile it
in the kernel to rule out problems with module loading ?
It works for me (tm), could you also give the complete grub lines ?
