Once AP's are launched, their MCA state information is stored and later obtainable using a sysctl. Since the size of the MCA state information is unknown, it will be malloc'ed as needed. However, when 'ia64_ap_startup' runs, it's not yet safe to call malloc and this may cause 'panic: blockable sleep lock (sleep mutex) 8192 @ /usr/src/sys/vm/uma_core.c'. This commit avoids this issue by scheduling a separate kthread to obtain this information, which immediately terminates afterwards. |
