Hi Brian,
Here is the output of "ifconfig -a", "prtconf -v" and "scanpci -v" commands.
Yes. your system does hit the CR.
I also came to know that there is another version of iwk packages version 1.1
released recently. Could you please, if possible, let me know if this problem
is fixed in that version? This one is available at
http://www.opensolaris.org/os/community/laptop/downloads/iwk-1.1-pkg.tar.gz
The new version makes the connect more stable, especially for chip
'pci8086,4229', just as yours. However, the problem you encountered is a
pci bridge & boot bug, not an iwk driver one. So the new version has no
relationship to the problem.
The workaround I send to you tries to manually modify the pcie bridge
configuration.
I Cc this email to [EMAIL PROTECTED], who I think is working on the
bugfix. Before the fix is available, you may try the workaround I send
to you and follow the instructions the workaround prompt to you.
I will try to install this package also to check if it helps. In the meantime,
you can send me the workaround, if available.
You can directly pkgadd the new version of the iwk though it does not
help to the current issue, then run the attached script and follow up
according to the instructions the script prompts to you step by step.
Any other questions, let me know pls.
Thanks,
Brian
Have a good day!
Regards,
V
