| |
Hi there,
With the earlier discussion about the eepro100 vs the e100, and with hotplug PCI going into the -ac series kernel, I think it's topical I discuss an APM related quirk.
If you buy a Dell Inspiron with the inbuilt ethernet option, you get a PCI eepro100. If you suspend and resume, however, the card seems to be in a funny state that an rmmod/modprobe won't fix.
I worked around the problem, by adding to the APM config this pre-suspend action:
ifdown eth0 rmmod eepro100
And to the resume action:
setpci -s8:4 4=17 5=1 c=8 d=20 11=f0 12=ff 13=fb \ 14=c1 15=dc 1a=e0 1b=fb 33=fc 3c=b ifup eth0
The setpci command was derived by comparing the contents of the PCI configuration area for that device before and after a suspend, and updating only the areas that changed.
Is this a job for `PCI hotplug', a eepro100 driver bug, or something else?
