| |
I have had problems with my SCSI disk in a number of 2.1.* kernels. I am not sure if there is a known problem as I haven't noticed discussions on this list.
In /var/adm/syslog I get the following:
Apr 11 13:33:18 udgaard kernel: HACC aha1542.c: interrupt received, but no mail. Apr 11 13:33:18 udgaard kernel: Sent BUS RESET to scsi host 0 Apr 11 13:33:18 udgaard kernel: Kernel panic: scsi_free:Trying to free unused memory
when trying to access the disk.
Everything is quite old (the 1542 and SCSI disk, 1991, PC system, 1994) so for a long time I thought that it might be the hardware that is failing, which may of course actually *be* the problem. I haven't been able to detect any problems using badblocks or other methods, though.
After the above message has appeared, I am not able to kill the processes that tries to access the disk, eg. df, neither kill -9 nor Ctrl-C. I am also not able to shut down the system with reboot or halt, and the three-finger doesn't do anything. I get the message "The system is going down for reboot NOW !!", but then nothing happens. I can only shut it down with the big red button.
The system is a 486DX2/66 GW2000 with a CMD640 and one WD ide disk plus the mentioned SCSI board and a Seagate HD. The kernel also has support for a NE2000 clone and that connection seems to work fine. I used to have SB16 support in, but using it as a module with the present module-problems, I haven't loaded it.
To help figure out if I have a hardware problem or a possible kernel problem, I am all ears for what to do further. For now I will have to revert to 2.0.33 that works very well for me.
Thanks,
Peter
