Summary: [2.5.69-bk14] Unable to handle kernel null pointer Kernel Version: 2.5.69-bk14 Status: NEW Severity: normal Owner: jsimmons@infradead.org Submitter: s.rivoir@gts.it
Distribution: Debian sid Hardware Environment: HP Omnibook XE3l Software Environment: kernel 2.5.69-bk14 Problem Description:
I get this everytime I run SVGATextMode with a resolution with more than 43 rows; I'm not sure that this failure it's a kernel bug, but I suppose it should not give this error anyway...
Steps to reproduce:
# SVGATextMode "80x50x9" <1>Unable to handle kernel NULL pointer dereference at virtual address 00000010 printing eip: c01be43c *pde = 00000000 Oops: 0002 [#9] CPU: 0 EIP: 0060:[<c01be43c>] Not tainted EFLAGS: 00013202 EIP is at vt_ioctl+0x1b3c/0x1d30 eax: 00000000 ebx: 000001e0 ecx: 00000000 edx: 00000000 esi: 00000006 edi: 0000000c ebp: 00000050 esp: c642fea8 ds: 007b es: 007b ss: 0068 Process SVGATextMode (pid: 342, threadinfo=c642e000 task=c6af0d00) Stack: 00000005 00000050 00000028 00000001 c01c6b90 00000009 00000028 c7113000 c66e7540 c642fedc c7639ca0 c71eb940 00000101 c7113000 00000001 00000000 c71eb940 c11e67bc 00000001 c6f95000 000003e8 c015630c 000003e8 c11e67bc Call Trace: [<c01c6b90>] con_open+0x0/0x90 [<c015630c>] vfs_permission+0x7c/0x120 [<c015223d>] get_chrfops+0x2d/0x90 [<c015258a>] chrdev_open+0x6a/0xc0 [<c0148b7a>] dentry_open+0x1ea/0x220 [<c01bc900>] vt_ioctl+0x0/0x1d30 [<c01b5e6c>] tty_ioctl+0x45c/0x570 [<c015ada0>] sys_ioctl+0x100/0x280 [<c010922b>] syscall_call+0x7/0xb Code: 89 58 10 66 85 ff 74 0a 8b 04 b5 60 7a 2f c0 89 78 68 89 34 Segmentation fault
