Subjectmassive filesystem corruption with 2.4.9
Hello.

Since linux-2.4.5 always the same errors occur sporadically after the cold boot
in the morning. (My computer is powered off during the night.) Every second
day I noticed my syslog sais something like the following:

Aug 21 09:01:06 adlib kernel: EXT2-fs error (device ide0(3,5)): ext2_new_block:
Allocating block in system zone - block = 3
Aug 21 09:01:06 adlib kernel: EXT2-fs error (device ide0(3,5)):
ext2_free_blocks: Freeing blocks in system zones - Block = 4, count = 1
Aug 21 09:01:06 adlib kernel: EXT2-fs error (device ide0(3,5)): ext2_new_block:
Allocating block in system zone - block = 37
Aug 21 09:01:06 adlib kernel: EXT2-fs error (device ide0(3,5)): ext2_new_block:
Allocating block in system zone - block = 45
Aug 21 09:01:07 adlib kernel: mtrr: base(0x42000000) is not aligned on a
size(0x1800000) boundary

Aug 21 09:01:30 adlib kernel: EXT2-fs error (device ide0(3,5)):
ext2_free_blocks: Freeing blocks in system zones - Block = 41, count = 4
Aug 21 09:01:30 adlib kernel: EXT2-fs error (device ide0(3,5)): ext2_new_block:
Allocating block in system zone - block = 4
Aug 21 09:01:30 adlib kernel: EXT2-fs error (device ide0(3,5)): ext2_new_block:
Allocating block in system zone - block = 7
Aug 21 09:01:30 adlib kernel: EXT2-fs error (device ide0(3,5)):
ext2_free_blocks: Freeing blocks in system zones - Block = 8, count = 2

Today it destroyed my super block and all my root-directories were placed in
/lost+found. I rescued everything with e2fsck-1.14 from a very old rescue-disk
and then again with 1.23, renaming and replacing the directories by hand. A lot
of devices and some .h-files were not recoverable.

These fatal errors are occuring since 2.4.5 (2.4.8 I've not tested.). When I
work with 2.4.4 everything is fine !

I already use the newest version of e2fsck (1.23) and util-linux (2.11f). My
RedHat (Rotkäppchen) 6.2 is rather old, but I don't like gcc 2.96 at all.

I posted this report as the errors occured after a complete crash with 2.4.6
also to the ext2-developers directly but they didn't answered.

Maybe you could help me here ?
