Bug 49811 – genkernel locks up while unmounting initrd

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Keith Lea 2004-05-03 00:36:27 UTC]

I'm using genkernel to build 2.6.6-rc3-mm1, currently I'm running gentoo-sources-2.4.22-r5. Genkernel freezes after saying "cleaning up and compressing initrd" and my computer goes into ~100% System CPU usage, being used by umount.

Here's the end of genkernel's log:

  INSTALL drivers/ieee1394/video1394.ko
  INSTALL drivers/pcmcia/yenta_socket.ko
if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.6.6-rc3-mm1; fi

* initrd: moving initrd fs to loopback

This has happened twice in a row, the second time was after rebooting, I assume it would happen every time.

Here are the genkernel arguments I used:

genkernel all --menuconfig --bootsplash --no-clean --no-mrproper --install --kerneldir=/usr/src/linux-2.6.6-rc3-mm1

This doesn't happen every time, only sometimes (maybe every other time). This is with the latest genkernel, version 3.0.2a.

Could you try building a kernel without genkernel? Let's narrow down a genkernel bug or a kernel bug.

[Comment 3 Tim Yamin (RETIRED) 2004-05-18 14:41:19 UTC]

This is a kernel bug - the system hangs when unmounting a loop...

[Comment 4 Greg Kroah-Hartman (RETIRED) 2004-06-21 13:36:55 UTC]

Does this happen on the 2.6.7-r2 kernel?  Or just with a -mm kernel?

[Comment 5 Daniel Drake (RETIRED) 2004-08-26 07:19:25 UTC]

Please retest with different/newer kernels as already requested, and reopen if this is still an issue.
