Comment 192 for bug 127101

Hi!

Not sure, if this will help you, but I can confirm this behaviour exactly on a HP Laptop (G 6000 series, G 6050EG) with NVIDIA graphics card with only shared memory.

It happens with the nv as well with binary nvidia driver (from repositorys and from the website).

I think it's related to ACPI, BIOS, IRQ stuff etc. Just guessing.

Very strange for me was, when typing e.g. "ls -la" in an non-graphical VT. By the third time doing this, the laptop would definitely freeze, no Sysrq, nothing. Can hear the hard drive shortly than the fan goes on, then no proof of liffe anymore. Just hard-reboot.

Also it happened when disabling the framebuffer with fb=false vga=normal.

I works for a while quite well when booting with (nosplash) noapic nolapic noapm pnpbios=off pci=conf1 noirqdebug
Sometimes VTs are still messed up, not readable text or just frame buffer "snow" and then freeze again.

Hope this information can help you. I guess this bug is not completely intel-driver-related, as my experience was. Tested also with live-cds from edgy and dapper and on feisty and gutsy installed systems.
