Zilog driver - auto-detect for no oopsen

Zilog driver - auto-detect for no oopsen

[David Eger]

I recently compiled  Linux Kernel v2.6.5-rc2-ben0 and...

Is there any auto-detection code we can add to the Zilog driver?

I accidentally enabled the  CONFIG_SERIAL_PMACZILOG option for my kernel,
and it crashes my powerbook all to hell when i try to put it to sleep...
I know the option is irrelevant for my hardware, but is Oops'ing really
what we want as a bad .config reminder?

hda: completing PM request, suspend
Oops: Kernel access of bad area, Sig: 11 [#1]

Hrm... that was supposed to be fixed. It definitely doesn't crash here
(the crash I fixed recently is on wakeup btw, not sleep).

I'd appreciate some debugging to figure out what exactly is going
on. It seems it accessing a wrong pointer but I fail to see what
precisely
