Current Issues
Quite substancial regressions from Breezy,
- Hotkeys no longer work
- Does not wake from suspend
- Does not wake from Hibernate
- Sdcard driver works unreliably (sdhci)
The following are serious regressions from breezy and render the laptop a lot less useful.

Notes
- [1] Sleep troubles:
The laptop successfully sleeps if I use GPM to click the suspend option. It sometimes sleeps if I shut the lid. Somtimes it does nothing (misses the event I guess).
It would appear from other reports that the pcc_acpi kernel module maybe busted -PaulSladen
I agree. I am tracking this in bug 35170. I thought that the solution was in 33855 but this was rejected -JohnStowers
- [2] Function Key Troubles:
The brightness adjsut keys can be used only once after the laptop has been started. E.g. turn on laptop -> brightness down (OK) -> Brightness up .... Nothing. Brightness down .... Nothing. They only work once. None of the other laptop function keys work. Ever
It would appear from other reports that the pcc_acpi kernel module maybe busted -PaulSladen
I agree. I am tracking this in bug 35170. I thought that the solution was in 33855 but this was rejected -JohnStowers
- [3] SD Card Slot:
Works (slowly)
Currently the driver only works in MMC mode. How slow is "slow"? -PaulSladen
About 20-30 senconds to transfer a 2mb image. About 3-5 mins to thumbnail 100Mb of pics off the card -JohnStowers
- [4] External Monitor
Using the i810switch utility works perfectly. I am unaware of any other easy means to enable the external monitor on this laptop.
Please file a bug against acpi-support with the ACPI event from sudo tail -0f /var/log/acpid when you press the key -PaulSladen
- [5] Bluetooth
Gnome-bluetooth-manager bails out with Traceback (most recent call last):
- File "/usr/lib/python2.4/site-packages/gnomebt/manager.py", line 274, in ?
- BTManager ().main ()
File "/usr/lib/python2.4/site-packages/gnomebt/manager.py", line 85, in init
- if not self.btctl.is_initialised():
gobject.GError: Can't get device id of hci0
This probably means the bluetooth module is not loaded which probably means that the bluetooth is not enabled. There's normally a key-combination of a "magic bit" that needs setting in the BIOS; please file a bug against acpi-support. -PaulSladen
