Hi, I've tracked down my bootproblems on a c3k with kernel 2.5.4x (e.g. 2.5.47-pa8) to the functions pdc_suspend_usb() [in arch/parisc/kernel/inventory.c] and pdc_pci_irt_size(&num_entries, 0); [in drivers/parisc/iosapic.c] which are both defined in firmware.c and work without problems in the 2.4 kernels. Anybody has an idea what's going on here ? Helge
