2010-12-16 22:42:35 carlos palma description Binary package hint: linux-image-2.6.37-8-generic I'm currently using the kernel 2.6.35-23 generic (the last known good kernel before upgrade from Maverick to Natty). It seams a possible regression (this Message is associated to source file "swiotlb.c" which have changed often since 2.6.35). But the "possible regression" problem appears to be between 2.6.35-23 and 2.6.37-6 (Alfa1 upgrade). I couldn't follow all the changes since 2.6.35 (at: http://www.linuxhq.com/kernel/file/lib/swiotlb.c). The laptop is a DELL Vostro 1700 (7700 dual core; 4GB ram). Also tested: - Fresh install of Maveric and then an clean upgrade to Natty A1 - Daily builds (since Dec/02) on USB shows the same kernel panic / boot stop The "/var/log/messages" file doesn't catch all the kernel boot log (see extraction below): Dec 9 00:17:29 localhost kernel: [ 0.000000] Initializing cgroup subsys cpuset Dec 9 00:17:29 localhost kernel: [ 0.000000] Initializing cgroup subsys cpu Dec 9 00:17:29 localhost kernel: [ 0.000000] Linux version 2.6.37-8-generic (buildd@allspice) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.1-10ubuntu3) ) #21-Ubuntu SMP Sun Dec 5 17:56:47 UTC 2010 (Ubuntu 2.6.37-8.21-generic 2.6.37-rc4) Dec 9 00:17:29 localhost kernel: [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-2.6.37-8-generic root=UUID=b165a793-8340-48f8-a2b4-091501e00083 ro debug vga=773 Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-provided physical RAM map: Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 0000000000000000 - 000000000009f000 (usable) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 000000000009f000 - 00000000000a0000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 0000000000100000 - 00000000dfe6d800 (usable) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000dfe6d800 - 00000000e0000000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000f4000000 - 00000000f8000000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000fec00000 - 00000000fec10000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000fed18000 - 00000000fed1c000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000fed20000 - 00000000fed90000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000feda0000 - 00000000feda6000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000fee00000 - 00000000fee10000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 00000000fff00000 - 0000000100000000 (reserved) Dec 9 00:17:29 localhost kernel: [ 0.000000] BIOS-e820: 0000000100002000 - 0000000120000000 (usable) Dec 9 00:17:29 localhost kernel: [ 0.000000] NX (Execute Disable) protection: active Dec 9 00:17:29 localhost kernel: [ 0.000000] DMI 2.4 present.
