--- Comment #29 from Olaf Gellert
I think the "activating device mapper" part of the bug is just what happens to be displayed when the hang occurs. It's likely that what's happening is that there is a race occurring in the kernel in the background. The wireless driver sounds like a reasonable culprit for that. Inserting a USB stick would change the probability of the hang occurring, as would fiddling with the ACPI options.
Well and just today my laptop hung again five times before booting successfully. A short look revealed that somehow the ipw-packets happened to be installed again on my laptop. After removing them, the thingie booted without hanging... Hmmm...
What we *really* need to track this bug down is a *full* sysrq+t trace, captured via serial console from another system. /var/log/messages will never contain the information we're looking for because 1) klogd hasn't started yet, and 2) the system is hung, so klogd wouldn't have been able to save the log anyway.
Yes, sure. I would really like to help out with that. But my laptop doesn't have a serial port, only USB. I guess a USB2serial converter does not help because it will not be active at this early stage of booting. Any suggestions what I can do to help?
