Testing one of our 2GB Dual-Pentium III (1ghz) machines we get a hard lock with kernel enterprise. kernel-enterprise-2.4.19.9mdk-1-1mdk.i586.rpm
The lock up seems to be related to the scsi driver. aic7xxx. The last message that is echoed to the syslog consol is: kernel: (scsi0:A:0:0): Locking max tag count at 64 after that the machine is dead. No ping, but keyboard works enough for Alt-SysRq stuff. Only problem is Alt-SysRq keys won't work. :( syncing the disk results in the machine "trying" (It starts to sync the disk) but will never finish, there is no HD activity. Then the keyboard will not respond anymore. Trying to get a process list, or memory stats will finish off the lock also. (as in it will become so useless that reset button is only thing working). If my first sysrq key is to reboot it will. I ran memtest yesterday and all memory is ok. Mandrake 8.1 has no problems on this machine. Heavy disk activity triggers the lock, like installing an RPM. :) It will always hard lock when installing the "FlashPlayer-5.0-8mdk" RPM. any suggestions? or specific sysrq keys you'd like me to try in locked up state? (there is no oops or anything like that on the consol window) -- Bryan Whitehead SysAdmin - JPL - Interferometry Systems and Technology Phone: 818 354 2903 [EMAIL PROTECTED]
