| |
Hello everyone,
Initially using a Seagate SATA drive I was experiencing random lockups, no kernel panic just a complete hang. Having read about issues with DMA and some Seagates I replaced the drive with a Western Digital Raptor. However I still see the same lockups. I've tried a variety of options to hdparm (based around -X70 -d1) none of them making any difference to stability. I then swapped to the libata driver expecting this to be more solid. It does appear to last a little longer than the IDE driver but the same problems manifest themselves. I then found that there were potentially some problems with the Asus board and shared interrupt lines to the SiI3112 so I upgraded the BIOS to the most recent version (1007). This has made no difference whatsoever. I also read that APIC and ACPI support could exascerbate this problem so I removed them from the kernel and disabled them in the BIOS. This has given better stability but still not to the point of a usable system. This is a desktop system and it will become locked if any heavy disk access is done. At the moment I'm running in PIO mode as this is the only stable way of handling the disk. I'm not doing any RAID and have no need to. Merely a boot of my 2.6.1/2.6.0/2.4.24 system to runlevel 1 and then running bonnie++ -u nobody will guarantee a hang before all the write checks have been completed.
Asus A7N8X Deluxe (nforce2) BIOS V1007, AMD Athlon XP (Barton) 2800+, 1GB DDR RAM (2 x 512 as Dual Channel), WD Raptor 36G SATA HD, Asus GeForce FX 5600 (256MB), Lite-On 52x CDRW, DVD-ROM. Fresh Gentoo build optimised for Athlon-XP (GCC 3.2.3 -march athlon-xp).
2.6.1 kernel patched for forcedeth and nvidia graphics card. APIC & ACPI support removed from kernel and turned off in BIOS. Both the IDE and libata drivers have been built into the kernel at separate times. It makes no difference what other applications are running.
I'm not on the list so a copy of anything posted would be much appreciated.
Thanks in advance to everyone working on the kernel - excellent stuff, it's been my working environment for years and a happy one at that!
Joe
