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 :

And if was bug, What kernel should I use to avoid this problem.

It could be the VIA chipset, but I'm not sure. One rule with the Linux kernel is you should (almost) always be running the most recent kernel before reporting a bug. This saves a lot of effort in tracking down bugs that have alreay been fixed.

It may be that Red Hat has already released a new kernel RPM since that time, or maybe you need to compile a new kernel.

Cheers, Andreas
