Tried blacklisting r8192se_pci wireless driver, no change. Its hard to get a dmesg of the actual error because I'm unable to write any form of I/O when it happens. Basically it's: DMA: Out of SW-IOMMU space for 8192 bytes at device 0000:08:00.0 DMA: Out of SW-IOMMU space for 72 bytes at device 0000:08:00.0 DMA: Out of SW-IOMMU space for 8192 bytes at device 0000:08:00.0 DMA: Out of SW-IOMMU space for 8192 bytes at device 0000:08:00.0 ... many many of these
Plus ext3 disk write failures and remount-ro event -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/856496 Title: DMA: Out of SW-IOMMU space on 8GB RAM Intel Mobile 4 Series Chipset Laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/856496/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
