I am having a strange halt troubles in my linux box after I installed the
2.4.20 kernel that didn't happen when I was running the 2.2 kernel.
The system works fine for hours or days, and then it halts. The keybord
halts, the remote acess halts, but I still can ping it !
I found some messages in this newsgroup with the same caracteristics, but it
was unsolved.
The system halts easily if I do a large I/O, like reindexing a database,
giving me some messages like: (scsi0:A:1:0): Locking max tag count at 128...
I have a Red Hat 9 distribution instaled in a Intel STL2 server board, with
2 Pentium III 933 Mhz and 512 Mb RAM, 2 scsi disks (18 Mb) and 2 IDE disks
(40 Mb), running in multiple RAID 1 and RAID 0 configurations.
The dmesg gives me the following data about the SCSI:

How I could know if this is a hardware problem or a kernel + module problem
?
Thanks
