I've just taken a look at the original dmesg and noticed something which could be significant:
[ 0.004000] PCI-DMA: Using software bounce buffering for IO (SWIOTLB) [ 0.004000] Placing software IO TLB between 0x20000000 - 0x24000000 Quentin, when you get the opportunity could you attach a new Jaunty dmesg captured without any workarounds in place, and also: uname -a sudo lspci -vvnn > /tmp/lspci-vvnn.log lsmod >/tmp/lsmod.log Secondly, would it be possible to try temporarily removing 2GB of RAM (I'm guessing the system has 2 x 2GB RAM modules) and seeing if the problem still occurs? With only 2GB of RAM the software bounce buffering required by Intel CPUs that have no IOMMU controller will not be used. The main test is to reduce total RAM to less than 4GB. -- Hardy 64-bit beta and nightly alternate installation stalls https://bugs.launchpad.net/bugs/217849 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
