This problem also seems to appear on 2.4.10-ac10 using the old AIC7xxx driver cdrecord spits out a bunch of errors, and after that the SCSI bus is just plain dead. The audio-cd itself can be played correctly on the PX-32TS using the front buttons. > Kernel version : Linux version 2.4.11-pre5-xfs (root@PowerBox.MysticWorld.de) > (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release / Mandrake Linux > 8.1)) #1 Mon Okt 8 13:38:15 CEST 2001 Kernel version : Linux version 2.4.10-ac10 (root@neve) (gcc version 2.95.4 20011006 (Debian prerelease)) #6 Tue Oct 9 11:59:30 CEST 2001 > I also tried stable and non-XFS kernels and the problem remains > > Shell command : cdrecord -toc dev=x,y,z (with a CDDA in the drive) > > My environment : AMD Athlon 900 Mhz > 512 MB RAM > 2 IDE hard drives > Plextor PX-32TS (the one which makes problems) > Plextor PX-W1210S > Adaptec 2940U2W SCSI controller (both CD drives attached) > nVidia Geforce 2 GFX (using XFree86 drivers) > ALSA sound system (0.5.10) with a SB Live!
