Unable to handle kernel NULL pointer dereference

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...

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!!

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...
