[gentoo-user] system freezes....

[Marco Calviani]

Hi list,
   i'm a Travelmate 8005 laptop user, running an updated gentoo box.
I'm routinely experiencing system freezes 1 or 2 times every two days,
without an apparent cause; everything stops, starting from mouse to
keyboard, so that it is impossible to restart the system.

The system logs of the system does not suggest anything particular
except for this:

hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdc: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0xec
hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdc: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0xec

which however i think it is related to cdrom issues.

# uname -r
2.6.14-gentoo-r5

(PS: i have a radeon 9700 video card wuth the latest (8.21.7) drivers)
# fglrxinfo
isplay: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON 9700 Generic
OpenGL version string: 2.0.5582 (8.21.7)

I know that these infos are completely insufficient but i don't know
where to start.

Best regards,
MC

I had very, very, very similar behaviour (cdrom-related error and 
failings on logs + random freezes) with a faulty power supply on my 
desktop machine.

Substituting the power supply cured all the issues, but I don't know how 
it can be done on a laptop.

yupp, kernel waits for some time outs, if you did not set unmaskirq with 
hdparm, this may make your laptop pretty unresponsive.
If this happens with all your cds, it is time to buy a new cdrom drive.

do you mean that i have to set the umaskirq option also for cdrom? I
had it set with hdparm only for my primary hd, that is /dev/hda.....
