Description Kristoffer 2008-04-02 00:19:13 UTC
I have noticed that booting takes much longer when generating the kernel's initramfs with genkernel-3.4.10_pre7 compared to the stable genkernel-3.4.9. The time taken for going to the Grub menu to the moment the LUKS passphrase prompt appears more than doubles, from 18 secs to 48 secs. From my investigation, it is only the "Loading modules" and "Activating mdev" that seems to take more time than usual. While these take approximately 30 secs with 3.4.10_pre7, they take 5 secs with 3.4.9.

Additionally, when I have generated livecd's using catalyst and genkernel-3.4.10_pre7 I have seen a similar increase in boot time compared to 3.4.9. But now the "Copying read-write data to tmp-fs..." (which is not used on my normal system, described above) also takes alot of extra time, rougly double what it normally does.

Switching back to genkernel-3.4.9 solves this issue in both cases.

Reproducible: Always

Steps to Reproduce:
1. Generate an initramfs with genkernel-3.4.10_pre7
2. Boot with the new initramfs

This does not happen any longer with genkernel-3.4.10_pre10. Case closed.

Thanks...

OK.  This is resolved in genkernel 3.4.10, which is now in the tree and stable.
