Bug 137750 – cupsd/usblp stops boot process on Kernel 2.6.16

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description mail 2006-06-23 09:41:52 UTC]

Hello,

I recently updated my Kernel from linux-2.6.15-gentoo-r1 to linux-2.6.16-gentoo-r9. I encountered the following problem:
* The init process stopped at "starting cupsd" randomly.
* I somehow found out (lsmod after successful reboot), that the module "usblp" wasn't loaded automatically anymore (by hot-/coldplug?).
* I added "usblp" to /etc/modules.autoload/kernel-2.6, so that the module is loaded before cupsd starts.
* I thought this should have fixed it, but today the init process stopped at "modprobe usblp".
* In both cases I was still able to reboot the machine with Ctrl+Alt+Del.
* Like said before, the problems occure randomly and only the very first time I boot Linux - never after a reboot.
* Everything went fine with the previous kernel version.

I tried to solve it by emergeing the newest cups version, without luck. I want to note that I use Turboprint, but nevertheless, I think it's rather an USB problem than cups'/the driver's fault.

Some information about my system:

(This was reported by cups when it interrupted the init process. I never got the message again after I put usblp in the autoload file. Now the boot process hangs earlier at modprobing usblp instead.)

(This is the partial output of dmesg after it booted succesfully).

I think this is a kernel issue, can you please update to 2.6.17 and tell me how it works?

[Comment 2 Stefan Schweizer (RETIRED) 2006-08-18 15:45:48 UTC]

please try with 2.6.17 and report

I'm currently running 2.6.17-gentoo-r4 and until today the problem didn't occur anymore.
