Subject: kerneloops.org report for the week of October 31 2009


This week, a total of 18023 oopses and warnings have been reported,
compared to 5816 reports in the previous week. This number and this
report only includes kernel 2.6.31 and later.

This week, the Ubuntu 9.10 distribution got released, which includes
kerneloops.org integration in the quality feedback system. I'd like
to thank the Ubuntu team for their effort in helping to get the quality
feedback about the kernel integrated into kerneloops.org.


One thing to note is that the Ubuntu 9.10 release ships with the kernel
debug option CONFIG_PM_TEST_SUSPEND enabled, causing many warnings to 
be submitted. This huge volume triggered me to split these reports, as well
as the check_bios_for_corruption() reports into a per machine entry.

The top 5 machines for which the suspend test fails:
   319 | suspend_test_finish(Latitude D830)
   231 | suspend_test_finish(XPS M1530)
   225 | suspend_test_finish(MacBook2,1)
   171 | suspend_test_finish(Compaq Presario CQ60 Notebook PC)
   157 | suspend_test_finish(Studio XPS 1340)

and there is also the very elegant 
   267 | suspend_test_finish(To Be Filled By O.E.M)


The top 5 machines where the BIOS corrupts memory:
    80 | check_for_bios_corruption(HP Compaq nx6110)
    69 | check_for_bios_corruption(HP Compaq nc6120)
    62 | check_for_bios_corruption(HP Pavilion dv6700 Notebook PC)
    49 | check_for_bios_corruption(HP Pavilion dv2700 Notebook PC)
    32 | check_for_bios_corruption(Compaq Presario F700 Notebook PC)


The report this week looks different from previous reports; the version
cut-off has moved to 2.6.31 so that a lot of older bugs now dropped out of the report.

New this week are some inotify bugs, that have been fixed in Linus' git tree after -rc5.
There's also an ext2 warning for when the user unplugs a USB stick, as well as the
usual binary and external kernel modules.

If you have (better) descriptions for some of these, let me know and I can add them to the
database.
