next in thread | raw e-mail | index | archive | help
I tried to update my machine form 2.2.2 to 2.2-STABLE (RELENG-2.2
tag). I compiled a new kernel and lkm's. My machine now hangs after
detecting my scsi adapter but before finding the root disk. I saw
similar behavior running 3.0-CURRENT in april, but was not able to
track down the problem. Any suggestions on the best way to debug the
problem? I have the full CVS tree and was think of slowly rolling
forward from 2.2.2 until I find the date where the 2.2 branch breaks
on my machine ( now what is the cvs command to do this?). In addition to
the kernel, lkm's and config are any other files needed to be synced
to build new kernels?
I have included the dmesg from my 2.2.2 kernel
and my current kernel config file. I seem to remember a probe
(bt0:0:0:0) as the last message before the machine hangs in new
kernels. I plan to add the DEBUG, DDB, and SCSIDEBUG options to my
config file before proceeding.
