Please note that the second hunk from 6259151 needs to be modified to cleanly apply to 6.1.103-rc1. Example on [1].

I think it happens when trying to access the ext4 root FS in the simulation, see for example [2] for more details. [2]: https://github.com/linux-ia64/linux-stable-rc/issues/3 From the call trace: ``` [...] [] die+0x1b0/0x3e0 [] ia64_do_page_fault+0x680/0x9c0 [] ia64_leave_kernel+0x0/0x280 [] dd_limit_depth+0x80/0x140 [...] ``` ...I tracked it down to [3] and following the linked discussion ([4]), this is actually patch 2 of 2. And 1 of 2 ([5]) is in upstream, but not in 6.1.103-rc1.
