My EeePC 1015PEM tends to block sometimes (approximately once per 2 days). Even _ cursor in (modesetted) text mode does not blink. After rebooting (unless battery and adaptor was removed) it shows the following messages from kernel (approximately 10 seconds after kernel boot):

I tried kernels from about 2.6.37 to 3.3. "irqpoll" option is already present in kernel command line. What can I do to fix/investigate the problem.

# cat /proc/interrupts # Note: this time it booted without that "nobody cared" message.

Can you paste the output of cat /proc/interrupts and lspci -vv? Also, check BIOS settings. Disable hardware you're not using and make sure to set the hard drive controller to AHCI. –  David Schwartz Mar 25 '12 at 20:10
    
BTW looks like the netconsole module is a charm against freezes: keeping the netbook Ethernet-connected to laptop for netconsole for 6 days - no freezes (it was approximately once per day before). –  Vi. Mar 31 '12 at 13:40
