Well, there *may* be more hidden secrets. The case has arrived at a point where you begin to think about the influence of moon phases or stray alpha particles.

Seriously: For the moment I am in peace again with my PC and not in the mood for more restart exercises. When I see the system's health degrading again I can of course try a next restart with a power-cycle for a change (so far I had made only soft reboots).

Or (though unlikely from your previous posts) a degraded RAID being rebuilt?
No RAID involved, it's just a single disk.
And per recommendation by someone else here I had already run a big 4-hours internal disk selftest without errors.

My main suspect is still some system (memory?) corruption, perhaps in connection with the discussed PAE "features". Another indication for this is that I had also unusual problems with Firefox in the same time: YouTube videos did not play any longer and it crashed completely when I shut it down before shutdown of the system.

No sweat. Most of us buy our computers for reasons other than using them as debugging exercisers.

Well said ....

While it has been my job and hobby for many years to diagnose and repair computer malfunctions, I am meanwhile much more content when they "just work".

I have a rig somewhat similar to yours but 'longer in the tooth', 8 gigs memory (using PAE) and a 1TB disk (stock 14.1)
Code:
# hdparm -i /dev/sda

/dev/sda:

 Model=WDC WD2500SD-01KCC0, FwRev=08.02D08, SerialNo=WD-WCAL74231724
 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
 RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=74
 BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=16
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=488397168
 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4 
 DMA modes:  mdma0 mdma1 mdma2 
 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: Unspecified:  ATA/ATAPI-1,2,3,4,5,6
Then
Code:
# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   3478 MB in  2.00 seconds = 1740.56 MB/sec
 Timing buffered disk reads: 172 MB in  3.01 seconds =  57.07 MB/sec
and finally
Code:
# dd if=/dev/zero of=/disk/tf bs=4M count=1000 conv=fdatasync #jfs in this case
1000+0 records in
1000+0 records out
4194304000 bytes (4.2 GB) copied, 85.4185 s, 49.1 MB/s
Not the sharpest knife in the drawer - but it will do.
