patch file for drivers/ide/pci/piix.c
Assigning to Kimball Murray, RH's onsite Stratus engineer. P. Created attachment 287571 [details]
Same patch as before
This patch generated against 2.6.18-59, and from above the base of the linux
tree.
Kimball, are the Stratus boxes in RHTS? If not, could you rig them up so I could use one of them? (I think I may have a better solution to this problem) P. Are Stratus' PCI IDs in the upstream kernel? P. Created attachment 289331 [details]
updated patch for piix.c to not claim Stratus ESB2 IDE device
Updated to include Alan Cox's suggestions.
Did you tried to use ideX=noprobe as kernel parameter? ideX=noprobe does not help, since we need the devices to be probed (and to be hotplugged). But we need to be able to replace piix.c with ata_piix.c in order to use libata. ideX=noprobe will avoid the built-in drivers/ide driver to probe a given address for a ide controller. pata_piix then will have the chance to control it, as it'll be built in as a module. If it works (I never tried) it'd avoid breaking existing setups (think hda -> sda) while allowing users to use the libata version. Created attachment 289797 [details]
patch file for drivers/ide/pci/piix.c
Modified the whitespace in the same patch as before, at the suggestion of
Prarit Bhargava.
Hi Prarit, any updates on this? Are you waiting for me to re-POST with with the whitespace changes? :) Repost with whitespace change please :) Thanks, P. Kimball/Prarit, did this get re-posted with the whitespace changes? Was reposted to RHKL a week or two ago. P. Prarit, unfortunately, it looks like there were pre-existing concerns from Alan and Aris that still need clearing up as requested from Don Zickus. It looks like Alan's patch in 230541 resolves this issue. His patch has been posted to RHKL. P. *** This bug has been marked as a duplicate of 230541 *** |
