I reported a bug some days earlier about problems with the enterprise
kernel, but not the same scsi driver(mine is sym53c8xx)
And as I said this did'nt happen with the old 2.4.5 kernel(from
mdk-cooker) it was running for almost a year, but now it's had a mem
upgrade and is running the kernel-enterprise kernel, and we've
experienced lockups with 2.4.18 and 2.4.19.
But this does'nt happen when using rpm, and the machine is alive,
responding to ping etc. but could'nt read from the disks, and happens
under high load(not very high, just compiling something could trigger it
), at first I thought it was a gcc-3.2 issue, but when trying with
kernel-enterprise-2.4.18.6mdk-1-1mdk this also happened, so I'll guess
this might be related
