It has helped and the laptop is able to suspend with the serial cable attached (further than before). It now panics on the first resume with the following (gdb output at bottom).
I think the serial cable is masking the problem as without it I can suspend/resume once and it only panics on the second resume. I guess I need the serail working to see that panic anyway.
You should do a quick grep through sys/dev/syscons for "= sc->cur_scp->index" and replace them all with the above NULL check. I'm interested if this will fix things.
Hi,
I fixed the other null derefernce in sc_bell() and the laptop is now suspending with the serial console the same as without.
Here is the output when I suspend the laptop (S3). After the first resume the laptop still works fine. When I suspend the laptop a second time no output is displayed but the laptop seems to suspend alright (according to the power led), but when it resumes it reboots straight away. Again no output on the serial.
Is there more debugging that I can turn on?
