Hello,
while running a perl script (as root), that reads through all blocks of my (active) swap partition I got the Oops appended below: (may be the answer is: Don't do that then!)
VFS: brelse: Trying to free free buffer last message repeated 14 times Unable to handle kernel NULL pointer dereference at virtual address 0000003e current->tss.cr3 = 00d84000, %cr3 = 00d84000 *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[<c01261c0>] EFLAGS: 00010206 eax: c0190002 ebx: c008a214 ecx: c008a214 edx: 00000006 esi: 00000000 edi: 080b6f70 ebp: c186bee0 esp: c186bd24 ds: 0018 es: 0018 ss: 0018 Process perl (pid: 3774, process nr: 38, stackpage=c186b000) Stack: c008a214 c186bf9c 080b6f70 c01263fe c008a214 c008a214 00000000 00000400 c01297fd c008a214 c1262640 ffffffea 00000400 c0b18e88 00000001 00000400 00000000 00001000 00000000 00000400 c0190812 00003dc6 00000000 c186be9c Call Trace: [<c01263fe>] [<c01297fd>] [<c0190812>] [<c0190002>] [<c019c8e1>] [<c019c95c>] [<c017cfff>] [<c0182f75>] [<c017cfff>] [<c011247c>] [<c01124b4>] [<c01a10d8>] [<c011247c>] [<c01124b4>] [<c0123b27>] [<c010a668>] Code: 89 42 38 8b 53 38 85 d2 74 06 8b 43 0c 89 42 0c 66 8b 43 04
