Lots going on here. First looking at the syslog file from Matt. I notice

Looks like we smashed our stack. This seems to be a separate issue
Based on the fail, I took a look at how gccgo handles stacks. It relies
on the split stack feature in gold, which doesn't appear to be
implemented for ppc64.
Running one of the go recursion testcases (attached) shows what happens
when we run out of stack and don't have the split stack feature to s
That image has massive filesystem corruption, it looks like it was
uncleanly shut down.

Your filesystem is corrupt, and based on previous bugs I suspect you may
have corrupted it by running QEMU twice against the one qcow file.

Canonical have been hitting issues with the System V semaphore code.

My guess is the card doesn't support 64bit DMA, it supports something
less than that. A quick hack in sound/pci/hda/hda_intel.c to disable
64bit DMA fixes it:
- if ((gcap & AZX_GCAP_64OK) && !pci_set_dma_mask(pci, DMA_BIT_MASK(64)))
+ if (0 && (gcap & AZX_GCAP_64OK) && !pci_set_dma_m
This is a multipath issue. The box has two cards with redundant paths to
each disk.
Multipath is meant to create /dev/mapper/mpath* devices, and the
installer should use them instead of the underlying /dev/sd* devices.

Talking to benh, the main issue in the PCIE hotplug driver.
Unfortunately that is not a module:
CONFIG_HOTPLUG_PCI_PCIE=y
Could we get that disabled in the ppc64le defconfig? We don't have any
hardware that needs it.

error recovery mechanism)
