I have an SMP pentium system, SCSI cdrom on ncr53c810 adapter. Playing files residing on cdrom with xmms (multithreaded graphical mp3 player) gives me reproducable hard system freeze. It happens when new file is opened, not every time but almost so. If I manage to switch from X screen to text console before this happens, I see this on the screen:
Code: 0f 0b 83 c4 0c f0 0f ba 2e 00 0f 82 89 bc 0c 00 83 fd 12 74 Aiee, killing interrupt handler
before that, there is a full screen of [<addresses>], not scrollable (keyboard driver does not work, neither SysRq nor scroll or switch VT). Addresses from bottom up are in these functions according to System.map:
c010a428: system_call (two bytes before ret_from_sys_call) c013941d: sys_read c015d7e8: proc_file_read c015f5cf: meminfo_read_proc c0136349: si_swapinfo c010a500: ret_from_intr (exect address) c010c3e4: do_IRQ c010c078: handle_irq_event c019f888: ncr_53c8xx_intr c019250b: scsi_old_done c0192c1b: update_timeout c0198c98: rw_intr c019350f: scsi_io_completion c019330e: __scsi_end_request c018c7b3: scsi_release_command c01930b5: scsi_queue_next_request c0193931: scsi_request_fn c018ccdc: scsi_init_cmd_from_req c010a57d: error_code c019b400: ncr_queue_command c019b400: ncr_queue_command (sic!) c019b481: ncr_start_next_ccb c020d787: RCSid (with "r" tag. Before goes "R scsi_device_types") c4802014: (outside the address range) c019b56f: ncr_put_start_queue c010a57d: error_code et cetera...
