Which is all normal, then:
***Mar 6 11:59:27 Webdesktop kernel: PCI: 00:10.3 PCI cache line size set incorrectly (32 bytes) by BIOS/FW. ***Mar 6 11:59:27 Webdesktop kernel: PCI: 00:10.3 cache line size too large - expecting 16.
Odd -- what kind of CPU does that have? That seems likely to be some kind of misconfiguration. Should be harmless, since it's not going to enable the feature that would then break.
Mar 6 11:59:27 Webdesktop kernel: ehci-hcd 00:10.3: init command 010009 (park)=0 ithresh=1 period=256 RUN
00:10.3 is the VT8235's USB 2.0 controller. There were no options in the
CMOS to configure the PCI cache line size, so I haven't been able to test
other values. Could it be that this issue is causing problems with the
EHCI (particularly reading data from the storage device)?
I'd more suspect that the errata on your VT8235 aren't the same as on mine ... if you haven't been seeing lost IAA statistics when you "rmmod ehci-hcd", like "(lost 223)", that'd be my guess as to why our results seem different.
