Dear All, I am using Linux 2.6.33.7 stable kernel + patch-2.6.33.7-rt29 to test OHCI interface on TI OMAPL138 platform. We observed that during bootup and OHCI init sequence the kernel hangs. If we use plane Linux 2.6.33.7 stable kernel Without RT patch then OHCI works fine. -------------Hang log -------------- console [ttyS2] enabled brd: module loaded console [netcon0] enabled netconsole: network logging started ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver ioremap ohci-regs=fee25000 ohci ohci.0: DA8xx OHCI ohci ohci.0: new USB bus registered, assigned bus number 2 ohci ohci.0: irq 59, io mem 0x01e25000 ======> Hangs here <========= -------------------------------------- Further debugging shows that the hang occurs within ohci_run() in drivers/usb/host/ohci-hcd.c file at below line, ohci_writel (ohci, val, &ohci->regs->roothub.a); Is is a known issue and someone has faced it before?
