PROBLEM: (BCSM91X60) (PATCH ID: OSF505-261) ******** This patch fixes simple lock time-outs and kernel memory faults that can occur with EV6 hardware and the itpsa driver. Stack traces look like the following: panic+228: stop_secondary_cpu(0xff800180) event_timeout+252: panic("event_timeout: panic request") xcpu_puts+76: event_timeout() printf+312: xcpu_puts() panic+584: printf() simple_lock_fault+492: panic("simple_lock: time limit exceeded") simple_lock_time_violation+24: simple_lock_fault() simple_lock_D+0: simple_lock_time_violation() WARNING: "st" irregularity: repeating frame: simple_lock_D+0 0 stop_secondary_cpu src/kernel/arch/alpha/cpu.c : 614 1 panic src/kernel/bsd/subr_prf.c : 751 2 event_timeout src/kernel/arch/alpha/cpu.c : 1183 3 xcpu_puts src/kernel/bsd/subr_prf.c : 895 4 printf src/kernel/bsd/subr_prf.c : 423 5 panic src/kernel/bsd/subr_prf.c : 804 6 trap src/kernel/arch/alpha/trap.c : 1760 7 _XentMM src/kernel/arch/alpha/locore.s : 1741 8 thread_dup src/kernel/arch/alpha/pcb.c : 638 9 itpsa_hba_go src/kernel/io/cam/iti/itpsacfg.c : 744 PROBLEM: (STL047529) (PATCH ID: OSF505-243) ******** The patch fixes a problem with some slower tape devices serviced by the itpsa driver by lengthening the timeout value used. PROBLEM: (87715) (PATCH ID: OSF505-303) ******** Fix for kernel memory fault. Stack trace fragment as follows: panic "kernel memory fault" trap _XentMM itpsa_hba_go
