Received an oops in the 2.4.2 kernel on an x86 SMP system, 640 MB RAM
(Compaq DL380 Server). The line of code this crashed on is in fs/dcache.c:
void d_instantiate(struct dentry *entry, struct inode * inode)
[snip]
--> list_add(&entry->d_alias, &inode->i_dentry);
Believe inode->i_dentry.next was equal to 0.
Sadly, am unable to reproduce this. Relevant part of .config at the end of
this message. Oops is below. I have a memory dump (from the lkcd utilities)
if anyone is interested. Please let me know if you would like more
information.
Please include me in replies as I am not on the mailing list. Thank you in
advance.
