We've moved to GRUB 2 as a development platform. Please can you check if this bug still applies there, and if it does, reopen it?

I had a similar experience (Toshiba laptop, SuSE 10.0, kernel 2.6.13, Grub 0.97)
After a large file copy operation, I hibernated my laptop and then attempted to resume. Grub gave the 'inconsistent filesystem structure'. Booting into another OS did not help, but booting into my 'Safe Mode' entry did.

I managed to reconstruct the problem, and traced it to the 'savedefault' line which was present in my main Linux and Windows entries. After editing the main Linux entry in the grub boot interface and removing the 'savedefault', I managed to boot just fine (with proper resume-from-hibernation and all file transactions completed afterwards).

My guess is that the 'savedefault' entry causes grub to try to access the filestructure of the partition on which the safedefault value is to be saved, and if that filestructure happens to be inconsistent at that moment, grub does not continue booting.

Would it be possible, in such cases, to have grub abort the saving of the 'savedefault' value but continue booting, possibly with a warning message and a 'press return to continue' prompt?

Once when I rebooted Linux on ReiserFS without proper shutdown (expecting that ReiserFS can recover from that), I was unable to boot Linux kernel using using GRUB --- it reported "Inconsistent filesystem structure".

It wasn't even able to execute "chainloader (hd0,1)+1; savedefault 1" command (with the same message), to load different operating system.

Only one of the entries for an old kernel actually worked, I booted into Linux using it, Linux did journal replay, and GRUB bootes all entries fine since then. I guess that ReiserFS journal replay code in GRUB is buggy.

The system is Suse Linux 10.0

I'm sorry I don't have the dump of that partition in unreadable state.
