Commit a3d3203e4bb40f253b1541e310dc0f9305be7c84 still fails to boot with same config.
Comment 5 Andrew Morton 2010-03-18 21:53:47 UTC
We really need to see the first screenful of that crash output so we can see where it crashed, please.

Perhaps you can play with the "boot_delay" kernel boot parameter to slow the output down, then photograph it just before the oops starts to scroll off the screen?

Perhaps you could also explore the earlyprintk support (Documentation/kernel-parameters.txt) or netconsole (Documentation/networking/netconsole.txt).

Thanks.

eth0 seems to get initializied later, so no console log via netconsole.

the parameter boot_delay (e.g. boot_delay=4000) has no influence on the output speed of the vga console!

Comment 8 Thomas Meyer 2010-03-26 17:17:13 UTC
this patch seems to fix the oops:
http://lkml.org/lkml/2010/3/26/41

May the bugs
https://bugzilla.kernel.org/show_bug.cgi?id=15600
https://bugzilla.kernel.org/show_bug.cgi?id=15518

are also fixed by above patch?

It's possible that these bugs are also fixed by the patch, but it would be good to verify that.
