From 2a3f6772aadbe378259c87c05ab6f091866b63ef Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Wed, 10 Apr 2013 16:48:16 +0000 Subject: linux-yocto/3.8: qemumips graphical boot Updating the meta SRCREV to fix and illegal instruction that is seen when launching X with USB pointing devices. meta/qemumips: build USB_UHCI_HCD into the kernel When booting qemumips and USB_UHCI_HCD built as a module, the following trace is seen, and then prevents X from starting: qemumips user.warn kernel: Call Trace: qemumips user.warn kernel: [] uhci_check_bandwidth+0x0/0x160 [uhci_hcd] qemumips user.warn kernel: [] uhci_urb_enqueue+0xba4/0xc48 [uhci_hcd] qemumips user.warn kernel: [<8058092c>] usb_hcd_submit_urb+0xdc/0x848 qemumips user.warn kernel: [<805b8fbc>] wacom_open+0x44/0x8c qemumips user.warn kernel: [<805a1990>] input_open_device+0xac/0xec qemumips user.warn kernel: [<805a8cec>] evdev_open+0x188/0x1bc qemumips user.warn kernel: [<802331d8>] chrdev_open+0xc8/0x1c4 qemumips user.warn kernel: [<8022b338>] do_dentry_open+0x248/0x2e4 qemumips user.warn kernel: [<8022b418>] finish_open+0x44/0x68 qemumips user.warn kernel: [<8023e51c>] do_last.isra.29+0x2c0/0xcbc qemumips user.warn kernel: [<8023efd8>] path_openat+0xc0/0x52c qemumips user.warn kernel: [<8023f840>] do_filp_open+0x4c/0xbc qemumips user.warn kernel: [<8022cc3c>] do_sys_open+0x128/0x20c qemumips user.warn kernel: [<8010c07c>] stack_done+0x20/0x44 qemumips user.warn kernel: Code: (Bad address in epc) qemumips user.warn kernel: ---[ end trace 8a48c6046870f8c2 ]--- Building the module into the kernel fixes the problem, but the root cause is still under investigation. The pipelines around jumps to module addresses seem to be triggering invalid instructions.
