It's hitting the BUG_ON() below
static void __shrink_dcache_sb(struct super_block *sb, int *count, int flags)
{
...
while (!list_empty(&sb->s_dentry_lru)) {
dentry = list_entry(sb->s_dentry_lru.prev,
struct dentry, d_lru);
BUG_ON(dentry->d_sb != sb);
...
Marcelo: could this be yet another pvmmu issue (bug #480822)? That fix only went in in -rc5.git1, whereas this is -rc3.git3
The dentry cache is corrupted. It could be the pvmmu bug, but it could as well be another source of corruption. Please try -rc5.git so the pvmmu bug can be ruled out. James, Can you please confirm the problem is not present on recent FC11 builds? Latest kernel seems to be kernel-2.6.29-0.197.rc7.fc11.x86_64.rpm Thanks Marcelo ... indeed I am no longer seeing this issue. Thanks! |
