Last working kernel?

Comment 6 Rico 2009-06-04 03:55:18 UTC

I think linux-2.6.27-gentoo-r8

Comment 7 Mike Pagano gentoo-dev

2009-06-10 00:39:27 UTC

Can you test with the latest development kernel which is git-sources-2.6.30_rc8 as of this writing.

Comment 8 Rico 2009-06-20 21:56:26 UTC

With this kernel:

Comment 9 Daniel Drake (RETIRED) gentoo-dev

2009-06-21 15:20:03 UTC

2 things to try:

1. Can you reproduce this when the vmware modules are uninstalled? (please make sure they are completely gone from /lib/modules and hence will not be loaded at boot -- unloading them after boot is *not* equivalent, make sure they don't load at all)

2. Can you reproduce this without uvesafb?

If the problem still occurs after the 2nd test, please post a new crash dump.

Comment 10 Rico 2009-06-23 20:04:39 UTC

without vmware is not so easy i must first set up a other computer for the vmware machines i try it tomorrow.


here without uvesafb:

Can you try the above patch?

It's included in 2.6.30.4, which is in genpatches repository, and should be available with the next 2.6.30 genpatches release.
