I have a Dell Inspiron 9100 laptop that has been crashing lately. It
seems to happen when there is a moderate disk load and the network load
is > 6 Mbits/sec. I can usually replicate it by running "portsdb -fUu"
while downloading or copying large files across the network. I have
tried the following in an attempt to isolate the problem, but nothing
has worked.
* disabling ACPI
* disabling hyperthreading
* disabling SMP
* switching back to the 4BSD scheduler from ULE
I ran kgdb against kernel.debug and the crash dump, but don't quite know
how to interpret it or where to go from here. I've attached my kernel
config file, dmesg.boot, and the outputs from kldstat and kgdb.
I recently upgraded my router/access point at home from 802.11b to
802.11g to take advantage of the faster network cards in my laptops and
I am wondering if that could be exposing a bug or race condition. I
tried putting my network card back in 11b mode (instead of 11g) and I
don't see the problem nearly as often.
Does anyone have any suggestions as to how to troubleshoot this further?
I have saved the relevant kernel files and crash dumps, in case I need
to reference them again.
