d-u today, amd64, after checking here for warnings, new grub files installed. Got through grub to boot, system panic. Reboot brought the increasingly familiar grub rescue. Sorry for a lack of further details, trying to restore now. Anybody else?

If the system (the kernel?) panics, where is the relation to grub?

I don't have any idea. I'm in the middle of trying to get a working system on that computer now. I just said what happened.

intel 32 here.

Same thing happened twice few days ago. I had to reinstall each time as I had no portable grub.

I would not call it a system panic, though. It's really a grub issue imo. Grub complained about some missing file, module or something, and then switched to grub rescue.

During d-u I was asked if I wanted to replace grub config files by the new ones (from the responsible of the packet). I didn't give the default answer, which is to keep existing config, and I chose "use the version of the package maintener". Maybe that is part of the explanation.

And grub is installed where? MBR? Partition?

grub is installed in the mbr. It wasn't a system panic, but panic was in one of the error messages. I wasn't asked questions though. During the install it appeared to run grub-update correctly and detected everything correctly.

I can not confirm the issue.
Just DU and reboot without any issue in 32 bit aptosid.

didn't save it, now all I get is up to grub-rescue prompt. Need to reinstall grub, it's not working out at all for me. Trying to restore grub using the aptosid install disk and following the manual's process. Looks like the install disk mounts all the partitions for me, but I guess I need to unmount them first and then follow the manual instrucitons for recovering grub in the mbr.

I unplugged the second drive I have and then got back to grub. grub tried to boot, failed at:

      Code:
starting hot plug event dispatcher: udevd
failed to read log page 10h


then bunch of error messages, then kernel panic.

Booted aptosid cd, set up chroot ok. Then apt-get instal --reinstall grub-pc got this:

      Code:
bash: apt-get: command not found
root@aptosid:/# ls
bash: /bin/ls: Input/output error]
root@aptosid:/@ more /etc/fstab
bash: /bin/more: Input/ouput error


So, I don't know, looks like the fs is fscked? I do have another partiton with an old version of sidux on it, and that boots fine. Is reinstall my only option? Fortunately I have a separate /home partition.[/code]

It seems that this error is related to your partition.
Boot the aptosid cd and execute the following command as root:
      Code:
 fsck -f -c -p [your partition]

Maybe fsck is able to fix this problem.
If not, you probably have a bigger problem, because some very important files are affected by this Input/Output Error (means that you can't read nor write/delete this file).

In case of critical I/O Errors I migrate my data (/home) to another partition and reinstall the system.
But I don't know how the experts in this forum would react.

EDIT: This threat should be moved to "Installation"

no, dont move it, its a valid upgrade warning, i have seen some cases on #aptosid, #debian and #debian-next
up to now it looks like, when asked if to accept the maintainers new version, its best to hit enter (i.e. keep the old one)
strange enough i didnt see that question either and all is fine on 3 boxes (32/64)

I'm running fsck -f -c -p /dev/sda5 now, seems to be taking a very long time, > 30 minutes so far. 50GB partition.
