Subject: Random IP27 Tests on 4.3.0-rc3
Date: Sun, 4 Oct 2015 01:06:03 -0400	[thread overview]
Message-ID: <5610B3BB.6090406@gentoo.org> (raw)

Has anyone else tested the below various kernel modes on IP27 hardware?  Same
observations?

CONFIG_SGI_SN_M_MODE=y
- Boots, works, until the hardlock bug bites.

CONFIG_SGI_SN_N_MODE=y
- Appears to boot, but crashes early.  This message is left on the MSC console:
    2A 000: *** TLB Refill Exception on node 0
    2A 000: *** EPC: 0xa80000000001d890 (0xa80000000001d890)
    2A 000: *** Press ENTER to continue.

CONFIG_MAPPED_KERNEL=y
CONFIG_REPLICATE_KTEXT=y
- Does not boot, give this classic (and annoying) error:
    Cannot load bootp():.
    Text start 0x1c000, size 0x1965a70 doesn't fit in a FreeMemory area.
    Unable to execute bootp()::  not enough space

CONFIG_REPLICATE_EXHANDLERS=y
- Appears to boot, but crashes early.  MSC error:
    2A 000: *** TLB Refill Exception on node 0
    2A 000: *** EPC: 0x0 (0x0)
    2A 000: *** Press ENTER to continue.


CONFIG_NUMA=y is true for all tests above, because that seemingly staves off
the hardlock bug a little longer....though mdraid seems to really exacerbate
the thing now.
