** Summary changed: - Kernel panic (hard lockup) on Asus Z37E with Hardy + [HARDY] Kernel panic (hard lockup) on Asus Z37E with iwl4965
** Description changed: - I feel a bit silly reporting this bug seeing as it's not consistently - reproducible. It just sort of happens on occasion. The only thing that - seems to be constant is that the computer's fairly busy when it happens - and rather than the CPU idling afterward, it goes nuts. By "goes nuts" I - mean the CPU fan spins up and *lots* of hot air come out. I've heard - idling is usually what happens after the crash. - - It's a laptop, always running in GUI mode, so no console for a - backtrace. No serial or com ports, so I can't use a serial console to - try to catch it. Even if I could, that whole thing about "not reliably - reproducible" would mean that even if I *could* rig a USB console to do - the job, I'd still need to find some way to reproduce it. - - I'd say this happens once every few days. This time, KVM was being very - busy, so that may have contributed, but it was the first time I've used - KVM and definitely not my first kernel panic on this system. - - I believe it's a kernel panic based on the fact that everything locks up - and the Caps Lock light is blinking (I have no NumLock or ScrollLock - light). Ctrl+Alt+Backspace, switching TTYs, and "Magic SysRq" are all - useless. I'm guessing the kernel is so hard-locked it won't accept any - interrupts. - 2.6.24-21-generic #1 SMP Mon Aug 25 16:57:51 UTC 2008 x86_64 GNU/Linux Ubuntu 2.6.24-21.42-generic Hardy 8.04.1 - There's nothing in dmesg, and nothing in syslog in the 18 minutes before - the crash (last thing being some iptables junk about a printer on - broadcast). + I bought this laptop from ZaReason. It is available with the Intel 4965 + 802.11n card or some other Intel card. I have the Intel 4965 802.11n + card. ZaReason says that nobody else has reported kernel panics with + this model laptop, but that few others have chosen the 802.11n option. + + The panics also have lately occurred just after boot or just after + resuming from suspend. I login, get to the desktop, start up some apps, + and then as soon as NetworkManager shows that it has connected...kernel + panic. ** Description changed: 2.6.24-21-generic #1 SMP Mon Aug 25 16:57:51 UTC 2008 x86_64 GNU/Linux Ubuntu 2.6.24-21.42-generic Hardy 8.04.1 I bought this laptop from ZaReason.

However, I've had 2 today, 3 on Saturday, 1 Friday, and 1 Thursday that I can remember. It seems since Intrepid was released, Hardy's stability with this chipset has plummeted. -- [HARDY] Kernel panic (hard lockup) on Asus Z37E with iwl4965 https://bugs.launchpad.net/bugs/278030 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
