#23 Kernel oops using rm on hfs volume
PowerCenter Pro 210mhz 604e, 224MB RAM, Linux 2.4-pre11 (rsync from Paul 12/8)
I was removing multiple files from my hfs drive, when I hit the BUG() at line 236 in /usr/src/linux/include/linux/dcache.h:
static __inline__ struct dentry * dget(struct dentry *dentry)
{
if (dentry) {
if (!atomic_read(&dentry->d_count))
BUG();
atomic_inc(&dentry->d_count);
}
return dentry;
}

I am looking at 2.4.3-pre8 source and it looks like this is
fixed there. Have you tried this on a later kernel?
