The http://www.kerneloops.org website collects kernel oops and
warning reports from various mailing lists and bugzillas as well as
with a client users can install to auto-submit oopses.
Below is a top 10 list of the oopses/backtraces collected in the last 7 days.
(Reports prior to 2.6.23 have been omitted in collecting the top 10)

This week, a total of 323 oopses and warnings have been reported,
compared to 110 reports in the previous week.

(This sharp increase is due to Fedora 9 alpha shipping the oops data
collection client in the default install, giving us much wider coverage
in the issues that actual users hit; many thanks to the Fedora project
for this)

With the 2.6.25-rc1 release out, this will be the last report that includes
2.6.23; future reports will only include issues from 2.6.24 and later.


Rank 1: set_dentry_child_flags
	WARN_ON at fs/inotify.c:172 set_dentry_child_flags
	Reported 93 times (116 total reports)
	This is a user triggered WARN_ON in inotify. Sadly inotify seems to be unmaintained.
	More info: http://www.kerneloops.org/search.php?search=set_dentry_child_flags

Rank 2: __ieee80211_rx_handle_packet
	WARN_ON at net/mac80211/rx.c:1704 __ieee80211_rx_handle_packet
	Reported 35 times (82 total reports)
	This is the well known packet alignment issue; fix in progress
	More info: http://www.kerneloops.org/search.php?search=__ieee80211_rx_handle_packet

Rank 3: remove_proc_entry
	WARN_ON at fs/proc/generic.c:736
	Reported 20 times (38 total reports)
	This WARN_ON is there if code tries to remove a non-empty /proc directory.
	Most reports are tainted, pointing at a bug in a binary module.
	Without the WARN_ON improvements from 2.6.25-rc1 it'll be hard to figure out which module is guilty.

Rank 4: bad_io_access
	WARN_ON at lib/iomap.c:44
	Reported 15 times (21 total reports)
	This is a bug in the ata_bmdma code
	More info: ...

I was never able to trigger this or get anyone to reliably trigger it with
a debug patch in. Which is why it has taken so long to fix. It looks like
kde4 is triggering this big rash of new reports.

Anyway, I have fixed a race or two and removed that warning code (which was

That's interesting.

Easy, I'll submit patch RSN.

to fix it or to print modules?
(the later is already done in 2.6.25-rc1, just not in 2.6.24 yet)
