Hardware sucks!

Since I stuck two more PCI cards into my PC, stability problems aroused with my TV card: When the system load raised while watching TV in fullscreen, the system froze randomly. In addition, after resetting my PC, the 150GB Software-RAID-5 array had to resynchronize itself. As I restarted the TV app while the sync was running, the system froze a second time. Resetting again, two of the three RAID-5 partitions had been marked as failed, such that the automatic reassembling at boot time failed - I couldn’t even do the assembling by hand! My whole data was lost!!

Even though I forced to assemble the working device with one of the failed devices, the data could not be reconstructed, neither with the one, nor with the other! What the hell was that thing about data redundancy with RAID-5!? In panic I rebooted from a Linux Live-CD and... the array reassembled itself! All data was there again! My oh my...!

At first I had IRQ problems in suspicion: USB and TV card are sharing the same IRQ. But after some experiments I still got those system freezes. Finally, I got the tip to try to switch from the capturing mode ‘overlay’ to ‘grabdisplay’, which seems to solve my problem.

A history of that problem can be read in this forum posting.
