I am adding this comment for others who searched under the phrase " modprobe timeout after 30 seconds during boot "
In my case, after noticing the slow boot, I installed bootchart and saw modprobe taking 30 seconds. Secondly, booting up with the kernel option "quiet" removed, showed that the system was "waiting for root filesystem" . The workaround above, https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.20/+bug/94981/comments/13 works for me. { However, the above blacklisting via editing /etc/modprobe.d/blacklist didn't work for me (no difference). And blacklisting via a blacklist file , e.g. echo blacklist ata_piix > /etc/modprobe.d/blacklist-ata_piix results in a a failed boot. } Also want to mention that, https://bugs.launchpad.net/ubuntu/+source /linux-source-2.6.20/+bug/106864/ has some similar information. -- Extremely Slow boot up PATA disk detected as sda https://bugs.launchpad.net/bugs/94981 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
