next in thread | raw e-mail | index | archive | help
Hi, all--
I've got a 1997 Dell XPS D300 which has been rock-solid over the years,
which I'd just upgraded via a PowerLeap iP3/T-1400C. The system seemed
stable for several days, so I cvsup'ed and updated this machine from
4.7p10 to 4.8-STABLE, only to get a panic a few hours later.
Can anyone make an educated guess as to whether the panic below is
related to this upgrade, or possibly more likely to be related to
disk/ATA issues? I mention the latter because the panic was preceded by:
May 14 07:06:44 <kern.crit> sec /kernel: ad2: READ command timeout tag=0
serv=0 - resetting
May 14 07:06:44 <kern.crit> sec /kernel: ata1: resetting devices ..
May 14 07:06:44 <kern.crit> sec /kernel: ad2: removed from configuration
May 14 07:06:44 <kern.crit> sec /kernel: done
...and I'd been using the chance of having the system case open to build
out another drive (ad2).

PS: I've seen a touch under a factor of three improvement in wall-clock
compiler performance-- "make buildkernel" went from ~1300 seconds down
to 450s. Which I think is pretty darn good for a $150 dollar upgrade,
or about 5% of the original system cost. The CPUID goes from:
CPU: Pentium II/Pentium II Xeon/Celeron (300.01-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x634 Stepping = 4
Features=0x80f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,MMX>
...to:
CPU: Intel(R) Celeron(TM) CPU 1400MHz (933.37-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x6b4 Stepping = 4
Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE>
...and is now running at 933 MHz due to the 66MHz FSB of the AL440LX
mainboard, rather than the normal 1400MHz @ 100MHz FSB of the Tualatin
[370PGA-FC Celeron2?] CPU being used. ECC memory still works, even.
