我在嵌入式linux(2.4)平台上运行jpeg2000压缩程序(jasper), 最初内存是64M ,程序提示out of memory 然后停职运行,我猜可能是内存少了, 因为这个程序在pc机上运行很好. 然后我将内存加到128M , 运行得到标题那样的错误. 然后向程序输入不同的参数运行又得到以下错误, unable to handle kernel paging request at virtual address ceb83bbd 我打开源代码看了看头就大了, 所以我想先向各位请教一个问题: 我的文件系统是只读的,这...

unable handle kernel paging request at virtual??求教 我改了内核代码,出了这问题,请问是怎么回事,如何解决?谢谢.
我在写驱动程序的init_module时, 想在其中,修改PCI地址a0000000的值, 但直接修改就出错." unable to handle kernel paging request at virtual address a0000000" 我以为是a0000000没有映射的原因,再ioremap(a0000000, PAGE_SIZE) 映射, 然后修改映射后的值,也是同样的错. :em06: 这种错是如何引起的啊??? 请帮忙!!
系统启动时报kernel panic,unable to handle kernel paging request at 08081f48 求助!
Thou shalt not follow the null pointer, for chaos and madness await thee at its end. Clearly the holy scriptures were mis-transcribed here, as the words should have been ``null pointer'', to minimize confusion between the concept of null pointers and the macro null (of which more anon). Otherwise, the meaning is plain. A null pointer points to regions filled with dragons, demons, core dumps, and...

Hi all, I found the following function, which is used to remove the head of a linked list. void RemoveHead(node **head) { node *temp; if (head && *head) { /* Corrected code */ temp = (*head)->next; free(*head); *head = temp; } } 1. Why is the purpose of 'head' in the 'if' condition? Shouldn't '*head' suffice? 2. This function has an argument, which is a po...
客户端与服务器建立了socket通信.当第一个客户端与服务器连接上后,便执行一些处理.此时,如果其它客户端要与服务器端连接、执行处理请求时,要在客户端显示服务器对第一个客户的处理还没完成. 也就是说一次只处理一个客户的请求,但要通知其它客户服务器正在处理前一个客户的请求. 编译都通过了,为什么执行到pthread_create(&pid, null, &handle_roution, null)这句时好象停住了,没有走进handle_roution(void *p)内部,我在handle...
