2.3.43 final Oopses when proftpd starts at bootup on my system. pre8 did
not do this. Oops as follows:

I'm guessing this is probably a result of or related to the following
change in the diff between pre8 and 2.3.37:
@@ -1233,7 +1235,7 @@
in_inode = in_file->f_dentry->d_inode;
if (!in_inode)
goto fput_in;
- if (!in_inode->i_op || !in_inode->i_op->readpage)
+ if (!in_inode->i_mapping->a_ops->readpage)
goto fput_in;
retval = locks_verify_area(FLOCK_VERIFY_READ, in_inode, in_file, in_file->f_pos, count);
if (retval)
Not sure how to fix it, but it's probably something silly/simple.
The "NETDEV WATCHDOG: eth0: transmit timed out" eepro100 problem I
reported before also still exists...it can be reproduced quite easily by
starting a ping flood ("ping -s 3000 -f foo") and waiting a second or so
for it to occur.
