Because the stable version of openafs does not compile with the stable kernel 2.6.25-gentoo-r6 yet, I tried to use openafs version 1.4.7. It crashes after variable time. Two examples of logged error messages are below: Example 1: ========== BUG: unable to handle kernel paging request at fffffffe IP: [<c038999b>] _read_lock+0xb/0x20 *pdpt = 00000000004aa001 *pde = 00000000004ab067 *pte = 0000000000000000 Oops: 0002 [#1] PREEMPT SMP Modules linked in: vmnet(PF) vmmon(PF) libafs(P) nvidia(P) Pid: 3992, comm: afsd Tainted: PF (2.6.25-gentoo-r6 #2) EIP: 0060:[<c038999b>] EFLAGS: 00010202 CPU: 3 EIP is at _read_lock+0xb/0x20 EAX: fffffffe EBX: 00000010 ECX: 00000001 EDX: f6f64000 ESI: fffffffe EDI: 4884b474 EBP: 4884b406 ESP: f6f65f80 DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 Process afsd (pid: 3992, ti=f6f64000 task=f7e34bd0 task.ti=f6f64000) Stack: f93d6da2 00000010 f6f65fb8 f93dcdd4 4884b474 00000001 f93cb8ac 00000000 4884b44f 4884b361 4884b474 4884a162 4884b474 00423db7 00000000 00000001 f9423db7 00000000 00000000 f9419937 f7e34db8 f9423db7 0000007b f9419690 Call Trace: [<f93d6da2>] afs_osi_TraverseProcTable+0x12/0x90 [libafs] [<f93dcdd4>] afs_GCPAGs+0x94/0x170 [libafs] [<f93cb8ac>] afs_Daemon+0x4bc/0x4f0 [libafs] [<f9419937>] afsd_launcher+0x2d7/0x6a0 [libafs] [<f9419690>] afsd_launcher+0x30/0x6a0 [libafs] [<c0103b43>] kernel_thread_helper+0x7/0x14 ======================= Code: 40 14 b8 00 01 00 00 f0 66 0f c1 03 38 e0 74 06 f3 90 8a 03 eb f6 5b c3 90 8d b4 26 00 00 00 00 89 e2 81 e2 00 e0 ff ff ff 42 14 <f0> 83 28 01 79 05 e8 fa fb ff ff c3 89 f6 8d bc 27 00 00 00 00 EIP: [<c038999b>] _read_lock+0xb/0x20 SS:ESP 0068:f6f65f80 ---[ end trace 3eb1061dd439e858 ]--- note: afsd[3992] exited with preempt_count 1 Example 2: ========== BUG: unable to handle kernel paging request at fffffffe IP: [<c038999b>] _read_lock+0xb/0x20 *pdpt = 00000000004aa001 *pde = 00000000004ab067 *pte = 0000000000000000 Oops: 0002 [#1] PREEMPT SMP Modules linked in: vmnet(PF) vmmon(PF) libafs(P) nvidia(P) Pid: 3972, comm: afsd Tainted: PF (2.6.25-gentoo-r6 #2) EIP: 0060:[<c038999b>] EFLAGS: 00010202 CPU: 3 EIP is at _read_lock+0xb/0x20 EAX: fffffffe EBX: 00000010 ECX: 00000001 EDX: f6f7c000 ESI: fffffffe EDI: 4884d172 EBP: 4884d129 ESP: f6f7df80 DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 Process afsd (pid: 3972, ti=f6f7c000 task=f7e09670 task.ti=f6f7c000) Stack: f93d6da2 00000010 f6f7dfb8 f93dcdd4 4884d172 00000001 f93cb8ac 00000000 4884d129 4884d04e 4884d172 4884c6ca 4884d13b 00423db7 00000000 00000001 f9423db7 00000000 00000000 f9419937 f7e09858 f9423db7 0000007b f9419690 Call Trace: [<f93d6da2>] afs_osi_TraverseProcTable+0x12/0x90 [libafs] [<f93dcdd4>] afs_GCPAGs+0x94/0x170 [libafs] [<f93cb8ac>] afs_Daemon+0x4bc/0x4f0 [libafs] [<f9419937>] afsd_launcher+0x2d7/0x6a0 [libafs] [<f9419690>] afsd_launcher+0x30/0x6a0 [libafs] [<c0103b43>] kernel_thread_helper+0x7/0x14 ======================= Code: 40 14 b8 00 01 00 00 f0 66 0f c1 03 38 e0 74 06 f3 90 8a 03 eb f6 5b c3 90 8d b4 26 00 00 00 00 89 e2 81 e2 00 e0 ff ff ff 42 14 <f0> 83 28 01 79 05 e8 fa fb ff ff c3 89 f6 8d bc 27 00 00 00 00 EIP: [<c038999b>] _read_lock+0xb/0x20 SS:ESP 0068:f6f7df80 ---[ end trace 68c1a72fe48a490c ]--- note: afsd[3972] exited with preempt_count 1 ----------------------------- #
