2.6.34 does not boot for me on this machine either, it times
out waiting for the boot device. However, it doesn't BUG.
I'm wondering if there are two issues, some issue which
showed up pre 2.6.34 causing this:
[ 5.854464] ahci 0000:00:1f.2: controller reset failed (0xffffffff)
and then something post-2.6.34 which triggers the BUG.
Googling for "controller reset failed" gives this:
https://bugzilla.kernel.org/show_bug.cgi?id=15744
on a similar machine, but that was fixed before 2.6.34.
Bjorn, could you tell me if this boot log shows anything
similar to the behavior you describe in that bug link?
Thanks in advance.
