| |
Hi all,
Ever since I moved to 2.6.0, I have been experiencing something I'd like to call scheduling problems while working in X. I have tried using preemptive mode, and turning it off, but the symptoms are the same:
whenever there is continuous disk access (e.g. tar, rsync, dd), X will not respond for a couple of seconds every couple of seconds. With that I mean that the mouse will freeze as well as all screen output, and then resume after a couple of seconds.
I wonder if I am the only one with that problem. The machine in question is a dual AMD 2400+ with 2Gb of RAM and a Maxtor DiamondMax drive spinning at 7200 RPM. The drive is configured as follows (hdparm):
multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 16383/255/63, sectors = 241254720, start = 0 Model=IC35L120AVV207-0, FwRev=V24OA63A, SerialNo=VNVD06G4C1NXZL Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=52 BuffType=DualPortCache, BuffSize=1821kB, MaxMultSect=16, MultSect=16 CurCHS=65535/1/63, CurSects=4128705, LBA=yes, LBAsects=241254720 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive conforms to: ATA/ATAPI-6 T13 1410D revision 3a:
I would appreciate any pointers to the source of the problem, or general hints!
