I don't know. I try to explain. With all debugging options enabled 2.6.21.x has never crashed. After two days 2.6.21.3 was running without any debug options, it has crashed. Tomorrow morning I will start that linux box with linux 2.6.21.3 without any debug options, and I will keep you informed (friday evening I have switched back to 2.6.21.3 with debug options enabled, so the machine doesn't crash during the week end: this system is my company firewall.) > Also, could you please send the dmesg, Jun 4 20:53:05 Pleiadi kernel: sanitize start Jun 4 20:53:05 Pleiadi kernel: sanitize end Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 0000000000000000 size: 000000000009ac00 end: 000000000009ac00 type: 1 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() type is E820_RAM Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 000000000009ac00 size: 0000000000005400 end: 00000000000a0000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000000ce000 size: 0000000000002000 end: 00000000000d0000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000000e0000 size: 0000000000020000 end: 0000000000100000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 0000000000100000 size: 000000003fdf0000 end: 000000003fef0000 type: 1 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() type is E820_RAM Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 000000003fef0000 size: 000000000000b000 end: 000000003fefb000 type: 3 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 000000003fefb000 size: 0000000000005000 end: 000000003ff00000 type: 4 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 000000003ff00000 size: 0000000000080000 end: 000000003ff80000 type: 1 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() type is E820_RAM Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 000000003ff80000 size: 0000000000080000 end: 0000000040000000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000e0000000 size: 0000000010000000 end: 00000000f0000000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000fec00000 size: 0000000000100400 end: 00000000fed00400 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000fee00000 size: 0000000000100000 end: 00000000fef00000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000ffb00000 size: 0000000000100000 end: 00000000ffc00000 type: 2 Jun 4 20:53:05 Pleiadi kernel: copy_e820_map() start: 00000000fff00000 size: 0000000000100000 end: 0000000100000000 type: 2 Jun 4 20:53:05 Pleiadi kernel: BIOS-e820: 0000000000000000 -
