Tracing with kdb shows that the system locks up right after executing this: (usb-ohci.c:2137) /* HC Reset requires max 10 ms delay */ writel (OHCI_HCR, &ohci->regs->cmdstatus); Anyone have any idea? The processor apparently never gets to the next instruction. [Cc: me please, I'm not on this list.] P.S. System chipset is ALi: 00:14.0 USB Controller: Acer Laboratories Inc. [ALi] M5237 USB (rev 03) (prog-if 10 [OHCI]) Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at 82400000 (32-bit, non-prefetchable) [size=4K] Shares IRQ with cardbus bridge and lcd controller. -- Taral This message is digitally signed.
