Greetings, A few days ago, Asrock released a new BIOS for the motherboard that I have been using as my primary test computer for the VT8235. The BIOS changelog doesn't specifically mention any improvements to PCI handling and everything else appears to be fairly unrelated (except for the USB boot which now works really well) - see http://www.asrock.com.tw/support/bios/Info/K7VT2_Info.txt
Since the update, the computer has not hang once during data read/write operations to the USB 2.0 HDD on the VIA EHCI controller. I thought this would have been the recent EHCI code if anything, but after reverting back to the previous version of the BIOS (1.20), the computer was back to writing perfectly, then hanging when the read operations were performed on the USB 2.0 HDD. The only way I could get it to hang was unloading and loading the EHCI driver twice - this is understandable and not normal practice. The VIA EPIA-M and EPOX are still two problem computers with the EHCI and may be suffering from something that the BIOS configures improperly. When I updated the BIOS, I ensured that all settings remained the same to avoid any confusion and the same IRQs are assigned to the same devices. Could this case provide any clues as to why the VT8235 still hangs like crazy on some computers? Is there any data that I can provide which may provide some clues? On my system that's currently running 2.4.21-pre5-ac3, here are some logs I created. The files starting in 120 are from the computer running the BIOS 1.20, and the files starting in 130 are those which are from the computer running BIOS 1.30: http://users.bigpond.net.au/linux/ehci/120_dmesg http://users.bigpond.net.au/linux/ehci/130_dmesg http://users.bigpond.net.au/linux/ehci/120_lspci-vvv http://users.bigpond.net.au/linux/ehci/130_lspci-vvv http://users.bigpond.net.au/linux/ehci/120_interrupts http://users.bigpond.net.au/linux/ehci/130_interrupts I intend on recompiling the kernel later on today with EHCI debugging messages; will these be of any help?
