Details of sys-kernel/mips-sources:

${m_name} Support has been marked as needing testing in this
ebuild revision.  This usually means that any patches to support
${m_name} have been forward ported and maybe even compile-tested,
but not yet booted on real hardware, possibly due to a lack of access
to such hardware.  If you happen to boot this kernel and have no
problems at all, then please inform the maintainer.  Otherwise, if
experience a bug, an oops/panic, or some other oddity, then please
file a bug at bugs.gentoo.org, and assign it to the mips team.
Heavy disk I/O on recent kernels may randomly trigger a VM_BUG_ON_PAGE()
in move_freepages() in mm/page_alloc.c.  The exact trigger cause is
unknown at this time.  Please report any oops messages from this
bug to bugs.gentoo.org (assign to mips@gentoo.org)
Things that might work, but have problems, or are unknown:
\t- CONFIG_TRANSPARENT_HUGEPAGE should work now, but there may still be
\t\040\040intermittent issues.  Additionally, CONFIG_HUGETLBFS must also be
\t\040\040selected for hugepages to work.  If use of this feature continues
\t\040\040to trigger random Instruction Bus Errors (IBEs), then it is best to
\t\040\040disable the functionality and perform a cold reset of the machine
\t\040\040after powering it down for at least 30 seconds.
\t- Serial support on the Octane uses a very basic UART driver that drives
\t\040\040the 16550A chip on the IOC3 directly.  It does not use interrupts,
\t\040\040only a polling routine on a timer, which makes it slow and CPU-
\t\040\040intensive.  The baud rate is limited to no more than 38.4kbps on
\t\040\040this driver.  Patches for getting the Altix IOC3 serial driver to
\t\040\040work (which uses DMA and supports faster baud rates) are welcome.
\t- UHCI Cards are known to have issues, but should still function.
\t\040\040This issue primarily manifests itself when using pl2303 USB->Serial
\t\040\040adapters.
\t- MENET boards appear to have the four ethernet ports detected, however
\t\040\040the six serial ports don't appear to get picked up by the IOC3
\t\040\040UART driver.  The NIC part number is also not read correctly
\t\040\040from the four Number-In-a-Cans.  Additional testing would be
\t\040\040appreciated and patches welcome.
\t- Other XIO-based devices, like various Impact addons, remain untested
\t\040\040and are not guaranteed to work.  This applies to various digital
\t\040\040video conversion boards as well.
