Hi!
I have very big black "notebook", with really small lid (and warning labels all around)... and have some problems with it.
First minor problem: upon boot, fan state becames desynchronized with what linux thinks; fan blows but cpu is cold. echo 0 > state; echo 3 > state fixes that.
What is worse, networking is slow. *Very* slow. Both on internal lan card and on hp100 I plugged into PCI. I'm getting 10KB/sec over 10Mbit ethernet. (That's 1% !). With acpi=off, it gets better... I get 100KB/sec (10%). Ouch. ksoftirqd eats 100% cpu with acpi off.
There's some very wrong with bttv on this machine. Radio works, tv tunning works and tv audio plays, but I can't get any picture:
root@hobit:~# cat /dev/video0 bttv0: reset, reinitialize bttv0: PLL: 28636363 => 35468950 . ok bttv0: timeout: drop=0 irq=195/237, risc=37cdf01c, bits: VSYNC HSYNC OFLOW cat: /dev/video0: Input/output error root@hobit:~# time cat /dev/video0 bttv0: reset, reinitialize bttv0: PLL: 28636363 => 35468950 . ok bttv0: timeout: drop=0 irq=198/240, risc=37cdf01c, bits: VSYNC HSYNC OFLOW cat: /dev/video0: Input/output error 0.00user 0.00system 0.53 (0m0.533s) elapsed 0.75%CPU root@hobit:~#
I was not able to get sata to work, so I'm running in some kind of legacy mode. Disk is slow, but I do not think it is related to strange problems. CPU frequency scaling seems to work okay, and both CPUs perform quite well. It is very fast on kernel compilation.
Any ideas what could cause those strange symptoms?
