| Product: | Gentoo Linux | Reporter: | Sebastian Fohler <info> |
| Component: | [OLD] Core system | Assignee: | Gentoo Kernel Bug Wranglers and Kernel Maintainers <kernel> |
| Status: | RESOLVED TEST-REQUEST | ||
| Severity: | critical | ||
| Priority: | High | ||
| Version: | 2005.0 | ||
| Hardware: | All | ||
| OS: | Linux | ||
| Whiteboard: | |||
| Package list: | Runtime testing required: | --- | |
Please try and reproduce on vanilla-sources-2.6.12_rc4 That could be a problem because its a productive system, but I will try OK - please reopen when you are able to test the latest development kernel (currently 2.6.12-rc5). If the problem exists there then we can form a bug report to send upstream. |
I changed my shmmax in /proc/sys/kernel to the value 1342117728 after that change I get segfaults on using some different programms, one is especially the use of emerge sync where I get this: Call Trace: [<c016bcec>] vfs_lstat+0x4c/0x60 [<c016c3eb>] sys_lstat64+0x1b/0x40 [<c0115740>] do_page_fault+0x0/0x649 [<c01032af>] syscall_call+0x7/0xb Code: 45 3c 5b 5e 5f 5d c3 8d 74 26 00 83 ec 18 8b 44 24 20 89 74 24 10 8b 74 24 24 89 5c 24 0c 89 7c 24 14 8b 58 10 8b 93 a4 00 00 00 <8b> 4a 3c 85 c9 74 29 89 44 24 04 8b 44 24 1c 89 74 24 08 89 04 <1>Unable to handle kernel paging request at virtual address 5046297c printing eip: c016bbb0 *pde = 00000000 Oops: 0000 [#22] PREEMPT SMP Modules linked in: e1000 CPU: 0 EIP: 0060:[<c016bbb0>] Not tainted VLI EFLAGS: 00010286 (2.6.11-gentoo-r6) EIP is at vfs_getattr+0x20/0xb0 eax: f3b65830 ebx: f3b68dc8 ecx: 00000000 edx: 50462940 esi: df289f6c edi: 000081a4 ebp: df289000 esp: df289ef0 ds: 007b es: 007b ss: 0068 Process rsync (pid: 9773, threadinfo=df289000 task=f7dba550) Stack: c592e680 dd631000 df289f6c 00000000 df289f18 000081a4 c016bcec c5940180 f3b65830 df289f6c f3b65830 c5940180 00000000 00020000 00000008 00000000 00000001 00000000 4255a09b 00000000 4267de32 00000000 00016ca6 00000000 Call Trace: [<c016bcec>] vfs_lstat+0x4c/0x60 [<c016c3eb>] sys_lstat64+0x1b/0x40 [<c01181a4>] sched_fork+0x24/0xc0 [<c0115740>] do_page_fault+0x0/0x649 [<c01032af>] syscall_call+0x7/0xb Code: 45 3c 5b 5e 5f 5d c3 8d 74 26 00 83 ec 18 8b 44 24 20 89 74 24 10 8b 74 24 24 89 5c 24 0c 89 7c 24 14 8b 58 10 8b 93 a4 00 00 00 <8b> 4a 3c 85 c9 74 29 89 44 24 04 8b 44 24 1c 89 74 24 08 89 04 <1>Unable to handle kernel paging request at virtual address 20666f20 printing eip: 20666f20 *pde = 00000000 Oops: 0000 [#23] PREEMPT SMP Modules linked in: e1000 CPU: 0 EIP: 0060:[<20666f20>] Not tainted VLI EFLAGS: 00010202 (2.6.11-gentoo-r6) EIP is at 0x20666f20 eax: c5940180 ebx: e3b68d48 ecx: 20666f20 edx: f0b69940 esi: dc86cf6c edi: bffff2ac ebp: dc86c000 esp: dc86ceec ds: 007b es: 007b ss: 0068 Process updatedb (pid: 22672, threadinfo=dc86c000 task=f7205a80) Stack: c016bbc9 c5940180 e3b67b90 dc86cf6c 00000000 dc86cf18 bffff2ac c016bcec c5940180 e3b67b90 dc86cf6c e3b67b90 c5940180 00000000 00020000 00000058 00000000 00000001 00000000 42680b59 00000000 42680b59 00000000 0004731d Call Trace: [<c016bbc9>] vfs_getattr+0x39/0xb0 [<c016bcec>] vfs_lstat+0x4c/0x60 [<c016c3eb>] sys_lstat64+0x1b/0x40 [<c01781a4>] __posix_lock_file+0x2f4/0x640 [<c01032af>] syscall_call+0x7/0xb Code: Bad EIP value. if I call dmesg after emerge sync.
