OK I was not able to reproduce this on a x86_64 box with > 7 GB of memory on 2.6.27.5-101.fc10.x86_64.
Do you guys have something like this on lspci: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub It seems the Intel 965 memory controller does IOMMU in software so I wonder if that is 100% correct if its the software for that. Not sure, just something someone pointed out to me. You can try these patches, the first one just clarifies the type of memory we want to deal with the second one makes it consistent. http://www.kernel.org/pub/linux/kernel/people/mcgrof/patches/ath9k/2008-11-14/ -- 2.6.27-2 kernel on intrepid: disk is mounted in RO after several hours https://bugs.launchpad.net/bugs/267089 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support.

Running last kernel 2.6.27-2 in intrepid results in having the disk to be mounted in read only after few ours of usage (about two from my experience). Disk works fine with another kernel. _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
