请教下：我的环境是 S3C2410+LINUX2.6.14，目前，SD卡和USB都可以用，现在遇到个问题，就是：<br />把SD卡挂到PC上当普通的U盘使用，读写都没有问题insmod g_file_storage.ko file=/dev/mmc/blk0/part1 stall=0 removable=1 。<br />但是，当卸载模块的时候就跑飞了：rmmod g_file_storage 后，kernel 就飞了：<br />Badness in kref_get at lib/kref.c:32 <br />Unable to handle kernel NULL pointer dereference at virtual address 00000008 <br />pgd = c3fe4000 <br />[00000008] *pgd=33f99031, *pte=00000000, *ppte=00000000 <br />Internal error: Oops: 17 [#1] <br />Modules linked in: g_file_storage <br />CPU: 0 <br />PC is at sysfs_hash_and_remove+0xc/0x150 <br />LR is at sysfs_remove_link+0x14/0x18 <br />pc : [<c00b172c>] lr : [<c00b34a0>] Not tainted <br />sp : c3db5ea4 ip : c3db5ec4 fp : c3db5ec0 <br />r10: beb07c58 r9 : c3db4000 r8 : c0221504 <br />r7 : 00000000 r6 : c024eaa0 r5 : bf006980 r4 : c024ea38 <br /><br />还请各位大侠多多指点啊，先谢谢了！！！<br />QQ 77291408 gg940231@163.com<br /><br /> |
