Re: R52 woes

I can't give you any clue on this, but I own an R52 (with the Intel graphics card) and it works 100% fine with Ubuntu. Maybe you should change to another distribution.

Hi!

Recently, I purchased a Thinkpad R52 (1847-W62) (lspci output attached).
Besides some really nice features and hardware components, few issues
constantly drive me crazy. Mainly, there are two problems.

* ATI driver
Well, this one is perhaps only a matter of time. However, I have tried
hard to get the recent driver (8.19.10) work flawlessly. After bootup I
see a real nice performance with DRI enabled. 3D Rendering works fine,
even moving and redrawing transparent aterms is much faster compared to
the Xorg driver. After suspending to RAM the laptop resumes sucessfully
with DRI still available. Waking up from suspending to disk works fine,
but invoking glxinfo results in a kernel oops:

[fglrx:create_buffer_queue] *ERROR* PCIe was not acquired
(complete oops attached)

X freezes, but the laptop is still accessible via network and can be
rebooted without problems. I posted this on http://ati.cchtml.com but up
to now got no response. On thinkwiki.org I found several reports about
successful suspend/resume with the latest ATI driver but no information
whether DRI is still working afterwards. So what is your experience on
this topic? While playing with the parameters in hibernate.conf I found
that any usage of vbetool would result in a complete freeze after
resume, so this would be no solution. In the meantime, the Xorg driver
allows for a safe suspend/resume.

* System instability
Currently, I stick to 2.6.12, with libata- & sata-pm-patches applied.
With 2.6.14 I had major problems using the dvd-writer. cdrecord listed
the device only once. Afterwards there were scsi timeouts and a garbled
output of cdrecord -scanbus. So the issues I have here might be kernel
related and vanish with a recent version. However, every now and then I
see freezes both at work (using the internal gigabit device -- tg3
driver) and ugly crashes with lots of oopses and segfautlts at home,
where I have a wireless network. The problems at home have (up to now)
vanished after applying the ipw2200 patch from
http://bughost.org/bugzilla/show_bug.cgi?id=821 . But at work the laptop
still hangs from time to time. Today I burned a dvd without errors, but
30% before finishing the next cd-r the box froze. A few days ago, I
needed three tries to finish a backup of the filesystem across the
network. In such situations I cannot log on via network but reboot the
laptop using the sysrq keys. I checked the memory (2x512MB) with
memtest86+ for 12 hours but found no error. With respect to the
displayed temperatures, the laptop does not get that hot (CPU ~53, GPU
~51, HDD ~35/40 acpi/smartctl; all degC). I also considered a defect in
the hardware (e.g.  a weak soldering point), but how to track this down?
Would IBM replace the mainboard or just the wlan card or the whole
device? What should I check before contacting the support? What causes
me real headaches is that I do not see any regularity in these failures.
I can run numbercrunching apps with the CPU temperature rising up to
72degC, stress the wlan device or copy several GB across the network and
nothing would happen. So any hints what to check next are greatly
appreciated!

Thanks for reading so far. Best wishes,
Torsten

my R 52 woes from time to time:
it freezes completely withing the forst 10 minutes of usage, otherwise I am able to use the maschine without any hassle!

I cannot tell exactly what it is, but I suspect cron, but I may be completely wrong!

  That happened to me a couple times when I was using the fglrx driver
included in Ubuntu Hoary (can't remember the exact version now).

>* System instability

On Monday I got my laptop back from IBM/Lenovo's service. The technician
told me that he had not found anything while running benchnmarks for
three days. I unpacked the device, waited some time as it seemed to be
rather cold in the delivery van, turned it on and after 30min it got
stuck again. Unfortunately, at that moment apt-get was unpacking the
libc-update... corrupted shared libraries -> system unbootable

Repair was successful and I decided to give 2.6.15-rc5 a try. The system
again froze while compiling the modules but behold! for about 16 hours
the laptop runs just fine! Even though I produce a pretty high load most
of the time the device remains up to now in a stable state. Well, I
don't want to be too overhasty, but I'm still somewhat optimistic that
the instability turn out to be kernel related ;)

With 2.6.15-rc5 only 3D acceleration remains an issue. Starting X(org)
with fglrx yields

 Bad page state at free_hot_cold_page (in process 'Xorg', page c134f5a0)

Using the r300 driver works better, even though at least one older
application crashes the session. Suspending works but resuming produces
a garbled screen. Without dri I see no problems. Does anyone have more
success with the r300 driver?

And there is another minor problem. When suspending to disk (swsup!)
there is the following timeout

 ata1: command 0xca timeout, stat 0x50 host_stat 0x20

Any idea about this one? Nevertheless, suspending is delayed by about 20
seconds and the device resumes flawlessly.

Cheers!
