PROBLEM: (MCPM40H5M) (Patch ID: OSF410-400255) ******** This patch fixes a problem that occurs on SMP systems using LSM in which the system panics with a "simple lock time limit exceeded" message. The problem is that the running process goes to sleep waiting for an LSM simple lock that never becomes available. A sample stack trace is as follows: > 0 stop_secondary_cpu(do_lwc = 0x0) 1 panic(s = 0xfffffc00005a1568 = "event_timeout: panic request") 2 event_timeout () 3 xcpu_puts() 4 printf() 5 panic(s = 0xfffffc0000572ea8 = "simple_lock: time limit exceeded") 6 simple_lock_fault() 7 simple_lock_time_violation() 8 voliodone() 9 biodone() 10 cdisk_complete() 11 xpt_callback_thread() The thread holding the lock: > 0 thread_block() 1 u_anon_faultpage() 2 u_anon_fault() 3 u_map_fault() 4 vm_fault() 5 trap() 6 _XentMM() 7 bcopy() 8 vols_volinfo() 9 volsioctl_real() 10 spec_ioctl() 11 vn_ioctl() 12 ioctl_base() 13 ioctl() 14 syscall() 15 _Xsyscall() PROBLEM: (QAR 63044, QAR 62998) (Patch ID: OSF410-405412) ******** This patch fixes a problem in lsm. A data corruption occurs when readv/writev coallesced via physio while in read/writeback mode. PROBLEM: (QAR 58063) (Patch ID: OSF410-405463) ******** voltrace sometimes prints records out of sequence. PROBLEM: (QAR 58073) (Patch ID: OSF410-405463) ******** volsetup would fail to add disks to LSM because the volboot file is full. PROBLEM: (QAR 62121) (Patch ID: OSF410-405463) ******** vold would dump core when a user attempts to add a 257th configuration copy to a disk group.
