Hi all, I'm facing something really weird. I'm currently using a P133, with a 3 years old 2940UW, on an old ASUS MB. The machine has proved being stable under 2.2.0-pre5. Recently I tried to use the PLIP module and couldn't insert the module the parallel port driver was compiled in. So I recompiled a kernel with the parallel port support (and PC HW version) compiled as a module. To my surprise, at the reboot the AIC7xxx driver hung in the following sequence: ----- aborting command due to timeout Pid 0 Scsi 0 channel 0 Id 0 Lun 0 Test Unit Ready 00 00 00 00 00 SCSI host 0 abort (pid 0) timed out -resetting bus is being reset for host 0 channel 0 SCSI host 0 abort (pid 0) timed out - trying harder ----- and the loop on trying harder goes on indefinitely. I didn't believe that the change on the inclusion or not of the ParPort would trigger the previous behaviour of the SCSI driver so I fetched pre6 and did two different compile on two different tree with the only single difference in the configuration being the following: ------ diff linux-2.2.0-pre6-1/.config linux-2.2.0-pre6-2/.config 55,56c55,56 < CONFIG_PARPORT=y < CONFIG_PARPORT_PC=y --- > CONFIG_PARPORT=m > CONFIG_PARPORT_PC=m 100c100 < CONFIG_PARIDE_PARPORT=y --- > CONFIG_PARIDE_PARPORT=m --------- After successful compilation and installation, I tried to reboot the linux-2.2.0-pre6-2 kernel and again the driver hung while the kernel linux-2.2.0-pre6-1 booted fine, so this seems reproductible. I'm puzzled, maybe there is some parallel port driver code initialization which change some setting on my motherboard. Can someone else reproduce this ? Even better can someone else explain and possibly fix that ?
