Package: udev
Version: 0.141-1
Severity: important
Following a large upgrade, my testing machine no longer boots correctly. It
appears
to hang, always at the same place, but will eventually continue. I have
determined
the following:
- The hang occurs after messages relating to the sound card and before messages
relating to the hard disk (the exact messages differ between kernels)
- Ctrl-C during the hang will allow the boot to continue
- It occurs with stock kernels 2.6.26-2-amd64, 2.6.28, 2.6.29, 2.6.30
- Rescue disks (testing of 04-Aug-2009 and 5.01) seem to boot correctly (the
testing disk only works in graphical mode, but the problem with text mode
doesn't appear to be the same, as the keyboard is hung also)
- The udev version on the testing rescue disk appears to be the same as that
installed
- Reinstallation of the udev package doesn't help
- Reinstallation of the kernel doesn't help (tested for 2.6.26-2-amd64)
- Booting with UDEV_DISABLED=yes doesn't hang, but other things maybe don't
work
afterwards (e.g. konsole doesn't reach a prompt) (tested with 2.6.30)
- bootchart seems to indicate that udev is holding things up and consuming near
100%
CPU most of the time
- dumping process information with sysrq during the hang lists udevd, vol_id,
path_id, events/3 and sleep among runnable processes
- on a single occasion, repeating error messages from mptbase were reported (I
didn't
note the exact message)
- fsck reports no issues on the filesystem
- Using Dell's bootable "Drivers and Utilities" disk to check the hardware
reported
no failures on any test, in particular there were no issues with the hard
disk or
sound card
- After adding udev_log="debug" in /etc/udev/udev.conf:
--- *many* console messages fly past during the hang
--- they include messages about sd_mod, bsg, block, so might indicate a disk
issue
--- if the boot is allowed to continue spontaneously, these messages do not
appear in the
system log, but several segfaults in udev are reported in the log
--- if ctrl-c is issued during the hang, several hundred megabytes of udev
messages are
written to the log
- googling for similar reports has not thrown up much (I have disabled the
floppy in
the bios and blacklisted the floppy module; booting with pci=nomsi does not
resolve
the problem either)
I am open to suggestions for how to decide whether this is a bug or a hardware
problem.
I have most of the debugging output mentioned above available, but some of it
is quite
large, so I shall await instructions on what to send or how to analyse it.
