[Bug 300193] Re: The realtime kernel is unstable on VIA MII (modules crash, i/o problems, does not shut down)

[Johan Ehnberg]

(note: these are from the stable 8.10-generic, ask for the -rt if
necessary as it requires some time on my part)

lspci -v:
01:00.0 VGA compatible controller: VIA Technologies, Inc. VT8623 [Apollo CLE266] integrated CastleRock graphics (rev 03)
	Subsystem: VIA Technologies, Inc. VT8623 [Apollo CLE266] integrated CastleRock graphics
	Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 12
	Memory at d8000000 (32-bit, prefetchable) [size=64M]
	Memory at dc000000 (32-bit, non-prefetchable) [size=16M]
	[virtual] Expansion ROM at dd000000 [disabled] [size=64K]
	Capabilities: <access denied>
	Kernel driver in use: vt8623fb
	Kernel modules: vt8623fb

And the X driver is openchrome, reporting:
(--) CHROME(0): Chipset: CLE266
(--) CHROME(0): Chipset revision: 17
(--) CHROME(0): Probed amount of VideoRAM = 65536 kB
...
(WW) CHROME(0): Manufacturer plainly copied main PCI IDs to subsystem/card IDs.
(--) CHROME(0): Detected VIA VT3122 (CLE266)-EPIA M/MII/....

I also noted a new thing in the jaunty kernel output: The CPU should be supported:
[    0.000000] KERNEL supported cpus:
[    0.000000]   Intel GenuineIntel
[    0.000000]   AMD AuthenticAMD
[    0.000000]   NSC Geode by NSC
[    0.000000]   Cyrix CyrixInstead
[    0.000000]   Centaur CentaurHauls
[    0.000000]   Transmeta GenuineTMx86
[    0.000000]   Transmeta TransmetaCPU
[    0.000000]   UMC UMC UMC UMC

/proc/cpuinfo snippet:
vendor_id	: CentaurHauls
cpu family	: 6
model		: 9
model name	: VIA Nehemiah
stepping	: 8
cpu MHz		: 1199.778
