Package: linux-image-2.6.18-3-amd64 Version: 2.6.18-7 Severity: grave Justification: hardware overheating hazard; requires periodic reboots (This is not the same bug as #400488 (upstream #7122)) This bug affects several amd64 notebooks from HP, notably the nx6125 and the nx6325; there may be other affected machines as well. Kernel team, please apply the patches for http://bugzilla.kernel.org/show_bug.cgi?id=5534 This bug is there merely to remind the kernel team not to release etch without the patches :) However I'm not sure which upstream version of linux, if any, contains the patches in the (long) trail of comments. So, it might be necessary to wait for a few days until the patches arrive in Linus' tree. Symptoms: - under load, the fans fail to turn on when the temperature reaches and then exceeds the normal threshold, which is 58°C. - there is a permanent memory leak in the kernel, even when the system is idle. The leak is visible by looking at $ grep Slab: /proc/meminfo and $ grep Acpi-State /proc/slabinfo Workaround: - if overheating, shut down the computer and let it cool down; or let it shut itself down to prevent a fire hazard. - if the only problem is the memory leak, reboot. Consequence: linux-image-2.6.18-3-amd63 (=2.6.18-7) is unsuitable for release. The memory leak is described at: http://www.mail-archive.com/linux-acpi@vger.kernel.org/msg03119.html Today I had to reboot my HP Compaq nx6325 because the kernel was eating 1.8 Gb out of the 1.9 Gb of RAM in the system, after about 9 days of uptime. Then I started a hourly cron job to monitor /proc/meminfo and /proc/slabinfo as described above: 2006-06-21T20:06:10: Slab: 30296 kB 2006-17-21T20:17:01: Slab: 37756 kB 2006-17-21T21:17:01: Slab: 48116 kB 2006-17-21T22:17:01: Slab: 55764 kB 2006-17-21T23:17:01: Slab: 69904 kB -- Reboot with acpi=noirq: only one CPU found -- 2006-24-21T23:24:10: Slab: 10444 kB -- Reboot with pci=noacpi: only one CPU found -- 2006-30-21T23:30:26: Slab: 9676 kB 2006-30-21T23:30:26: Acpi-State 0 0 80 48 1 : tunables 120 60 8 : slabdata 0 0 0 -- Reboot with no options: OK, both CPUs found -- 2006-34-21T23:34:23: Slab: 10584 kB 2006-34-21T23:34:23: Acpi-State 0 0 80 48 1 : tunables 120 60 8 : slabdata 0 0 0 2006-17-22T00:17:01: Slab: 15424 kB 2006-17-22T00:17:01: Acpi-State 23088 23088 80 48 1 : tunables 120 60 8 : slabdata 481 481 0 2006-17-22T01:17:01: Slab: 29956 kB 2006-17-22T01:17:01: Acpi-State 59136 59136 80 48 1 : tunables 120 60 8 : slabdata 1232 1232 0 I'm more than willing to help test a kernel package, but I'll be on [VAC] from 2006-12-23 to 2007-01-03 inclusive. So, please do not release Etch just now :) -- Ludovic Brenta.

I've commited Steve's fix to this bug which includes the description of the issue. Furthermore, I've updated his patch to reflect some additional models (mentioned in the kernel's bugzilla but not in Debian's) and to point also to the other ACPI issue (Kernel's #7122 and Debian's #400488) Regards JavierAttachment: signature.asc
