Package: initramfs-tools Version: 0.130 Severity: important Hi.
The following is a quite strange problem, and it may actually be a kernel bug. Few days ago, I got a new notebook (a Fujitsu U757), before I removed the HDD from the old one, I changed MODULES=most on the old and updated the initramfs. This was with kernel 4.13.4-1. Then I moved the HDD to the new notebook, and everything worked fine. Yesterday I've upgraded to 4.13.4-2 and then during booting the system freezes. First I thought it must be because of the kernel, but after some trying, I remebered that I've changed MODULES back to =dep and may not have put an updated initrmafs in place. Downgrading to the older kernel, and trying with dep seems to confirm this. The system freezes as well. Some further detail: My system is fully encrypted with dm-crypt and I boot from a USB stick. So the kernel, initramfs and a gpg-encrypted key is on the USB stick. (I don't use the keyscripts from Debian as they have issues, but my own basically just mounts a device by UUID, asks for a password and tries to decrypt the file from the device, which contains the key). This is also why my /etc/initramfs-tools/modules contains the modules for USB. Now, when I boot with a initramfs created with MODULES=dep, it goes until my keyscripts asks me for the password (which means that the fs on the USB stick must have been found mounted and unmounted already (this is done with passdev from cryptsetup, which mounts, reads the key file and unmounts)). At that pount (the password prompt printed) the system is frozen. No keyboard activity, nothing printed to the konsole when I remove or add e.g. USB sticks, MagicSysRQ doesn't work either. The only thing that helps is a hard power down. On some (but not all occasions) I saw some graphical distortions on the screen, e.g. parts of a character row overwritten by a small black line. As soon as I use MODULES=most, everything works fine again. >From the behaviour I'd say there is some kernel bug here as well, as it freezes and doesn't even panic or so. Feel free to immediately reassign to the kernel if you agree. I'd be greateful for any other advice on how to debug this. Cheers, Chris. -- Package-specific info: -- initramfs sizes -rw-r--r-- 1 root root 14M Oct 17 01:33 /boot/initrd.img-4.13.0-1-amd64 -- /proc/cmdline BOOT_IMAGE=/vmlinuz-4.13.0-1-amd64
