Hi, can anyone decipher the following kernel messages. These occur when I put a DVD in the drive and it tries to mount and fails. I previously had Suse 10.1 on my HP Pavillion laptop but have recently switched to Ubuntu 6.06. These messages don't occur with pre-recorded media (mag cover discs) and don't occur with writable media burnt in other computers. Media previously burnt under SuSE which read fine under SuSE, now don't read under Ubuntu but media burnt under Ubuntu does read in other computers but not this one. It's quite bizarre - it seems if it was burnt in this laptops burner, however long ago, under whatever Linux version or with whatever media brand, they now don't read but do in other computers?
Mmmm, maybe the reading laser on my DVD drive has had it? But how come it can read writable media burnt in other computers?
I tried turning off dma with hdparm but no difference:
martin@linux-laptop:~$ sudo hdparm /dev/hdc Password:
/dev/hdc: IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument
Anyone experienced anything like this before, particularly with a dying DVD burner perhaps?
Thanks & best regards,
Martin
Hi Martin I cannot decipher kernel message, but have had similar problems with Suse 10.1. Dvdwriter stopped writing on Suse and failed to read some CD/DVD's bought new DVD rewriter, that also failed to funtion correctly. Tried it on Etch, and Gentoo, fully functional, also tried old one on same, fully working. When writing, on Suse it would "commence write" then immediatly "close session" K3b gave "unknown error" I believe this problem, with me, commenced with Suse after last update.
