基于PDC1000开发的接口板(使用PCI9052)。 数据采集有两部分,第一部分较少数据读写;第二部分大量数据频繁读写(80ms定时器,每80ms有2048次*3*12位/次,时钟由2M晶振产生,瞬间读写速度大概2-3M/s),但这80ms只有20-30ms有读写。
电脑开机马上(电脑开机2,3分钟即进行)连接测量仪器,第一部分数据读写没问题,采用第二部分读写会出现电脑自动重启。
windbg分析dmp文件是f4错误。(网上请教说是:This system bugchecked when the critical process csrss.exe failed an I/O operation due to insufficient non-paged pool. 应该是发生了内存越界之类错误)

Several processes and threads are necessary for the operation of the
