Public bug reported: Binary package hint: linux-image-386
Actually it seems that the ide=nodma parameter has no effect when booting into the latest (2.6.28-6-386) kernel in jaunty. I am booting from a CF card using a IDE<->CF Adapter which does not support DMA. I get a lot of errors like this: [ 116.356217] end_request: I/O error, dev hdb, sector 595 After a while, the kernel informs me then that DMA has been disabled, although specyfing ide=nodma (hdb=nodma didnt work either) I never asked the kernel to ever enable it. Maybe these lines are also interesting: [ 0.007288] Working around Cyrix MediaGX virtual DMA bugs. [ 19.550485] ide0: BM-DMA at 0xf000-0xf007 [ 19.550753] ide1: BM-DMA at 0xf008-0xf00f According to the last post in this thread (http://ubuntuforums.org/archive/index.php/t-9914.html) a possible solutions seems to be as follows: -- Open the file "drivers/ide/ide.c" in the kernel source directory. In this file, there's a global variable defined. Look for int noautodma = 0; and set it to 1. That's it. -- This solution is of course inacceptable, I am not willing to patch the Kernel and maintain a custom Kernel image just because a boot parameter is not working. ** Affects: linux-ports-meta (Ubuntu) Importance: Undecided Status: New -- ide=nodma has no effect https://bugs.launchpad.net/bugs/367420 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
