[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Cannot boot PVH dom0 with big initrd
Hi,
After fixing the xhci crash, I hit another issue - booting with 236MB
initrd doesn't work, I get:
(XEN) [ 3.151856] *** Building a PVH Dom0 ***
...

If I skip initrd, then it boots just fine (but dom0 is not happy about
that). 164MB initrd failed too, but 13MB started ok.
Just in case, I tried skipping XHCI console, but it didn't change
anything.
Host has 16GB of memory, and there is no dom0_mem= parameter. Xen is
started from GRUB, using MB2+EFI.
When it works (12MB initrd), I get the following info:
