Hi all,

I am using RH 7.1 with the stock 2.4.2-2 kernel, I got several times my
disk corrupted and even lost the superblock. I have seen a lot messages
about the ext2fs corruption in kernel 2.4.2 but I didn't find what was
causing this problem (hardware or sofware). And if was bug, What kernel
should I use to avoid this problem.

I got these error messages :

EXT2-fs error (device sd(8,8)): ext2_new_block: Allocating block in
system zone - block = 786920
EXT2-fs error (device sd(8,8)): ext2_new_block: Free blocks count
corrupted for block group 3
EXT2-fs error (device sd(8,8)): ext2_readdir: bad entry in directory
#768546: rec_len is smaller than minimal - offset=0, inode=0, rec_len=0,
name_len=0

Here is the the output of   lspci -vv :
