Re: Instability w/ 2.6.6
FWIW, same type crash issue with 2.6.6. Used my 2.6.6-rc2 config with no 4kstack, no regparm. 2.6.6-rc2 has run for weeks at a time with no issues.
Have tried the acpi_skip_timer_override suggestion - still crashes.
Rebuilt the kernel with ACPI removed - still crashes. (also acpi=off & noacpi)
It sometimes will not even make it through the disk check on boot. Sometimes to X (w/5336) and then crash/hang
Abit NF7-S v1.1
nVidia Corporation NV15 [GeForce2 GTS/Pro]
2 x Maxtor disks (old ones as some new ones with 8Mb buffer have issues)
No joy for now - back to 2.6.6-rc2. Will look further later.
