Hi there: As suggested in the docs, I am forwarding a bug report. I have just converted two partitions to ext3 from ext2 without reformatting on my home box. All is not well, however. Here's the specs AMD K6/2-3D 500 Mhz, 64MB SDRAM, 100 Mhz bus Via Apollo P5MPV3 chipset, 100 Mhz bus Opti Mad 16 931 soundcard Video= AGP S3 Trio, w/8MB RAM, PS/2 mouse. Realtek 8029 pci bus network card. Award BIOS 56K external modem on /dev/ttyS1. PS/2 mouse. /dev/hda=2.5 Gig Maxtor 82560A4 drive(windoze 95) /dev/hdb=6.4 Gig Fujitsu MPC 3064AT Drive Unused usb ports. [root@genius /root]# hdparm /dev/hdb /dev/hdb: multcount = 2 (on) I/O support = 1 (32-bit) unmaskirq = 0 (off) using_dma = 0 (off) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 784/255/63, sectors = 12594960, start = 0 I have 2 large partitions on /dev/hdb for linux which are now ext3. Before the conversion, and still with a 2.4.3 kernel (not ext3 capable) hdparm -tT reutrns 37MB/sec & 10.5 MB/sec respectively; After converting as per the mini howto (Using defaults), and updating the kernel to 2.4.18, hdparm -tT returns 37MB/sec and 6.5MB/sec. What's worse, in a console, I get this error repeated many times invalidate: busy buffer but in an X terminal, I don't see it at all, although the speeds are similar. Is this dodgy hardware, kernel, or what? Where should I look for a fix? Please copy me direct - I'm not subscribed to this list yet - inbox blues. hdparm -d1 refuses to set dma [root@genius /root]# hdparm -d1 /dev/hdb /dev/hdb: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) The system is Mandrake 8.0.
