Hi All,
I've received the following suggestion:
In /usr/src/linux/drivers/pci/quirks.c remove text beginning from this line:
static void __devinit quirk_via_cx700_pci_parking_caching(struct pci_dev
*dev)
Until this line (remove this line too)
DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_VIA, 0x324e, quirk_via_cx700_pci_parking_caching);
Then recompile the kernel and reboot with it.
I have taken used kernel version 2.6.28.10. Then I've rebooted my Pentium3
box with it. Unfortunately this PC still rebooted after accessing /dev/video0
Then I moved the hard drive and the PVR500 to my Athlon1700+ and also booted
kernel 2.6.28.10. Same result, this PC also rebooted after accessing /dev/video0
I have attached dmegs from the Athlon, and lspci from both PC's.
Does anybody have an idea howto proceed from here?
I will repeat the above test with the newest kernel source and report back.
Best regards,
Cedric
