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
