With kernel-2.4.18-x i also have some troubles with the keyboard in X11. Indeed, the automatic repeat of the keys is sometimes really excessive. This is particuliairement remarkable with multi-gnome-terminal when i presse the keys [sift]+[->] or [<-] to switch between terminals.
I have swaped the disks between my two ide cards. before : VP_IDE: VIA vt8233: hda: WDC WD205AA-00BAA0, ATA DISK drive hdc: SAMSUNG CD-R/RW SW-240B, ATAPI CD/DVD-ROM drive hdd: CREATIVE DVD-ROM DVD1243E, ATAPI CD/DVD-ROM drive HPT370: hde: Maxtor 90340D2, ATA DISK drive hdg: Maxtor 90340D2, ATA DISK drive now : VP_IDE: VIA vt8233: hda: Maxtor 90340D2, ATA DISK drive hdc: Maxtor 90340D2, ATA DISK drive HPT370: hde: SAMSUNG CD-R/RW SW-240B, ATAPI CD/DVD-ROM drive hdf: CREATIVE DVD-ROM DVD1243E, ATAPI CD/DVD-ROM drive hdg: WDC WD205AA-00BAA0, ATA DISK drive This solve my problem when copying file between two disks. I do some tests with kernel linux-RH-2.4.19-0.pp.9 and linux-2.4.20-rc1-ac1. I have less ofen freeze. linux-2.4.20-rc1-ac1 is more reliable. However, i can not mount cdrom, and it spend two more cpu usage when i play avi file with mplayer. Currently only kernel-RH-2.4.17-0.1 can be use "safety" with my computer. With others kernels i can't get an uptime greater than 2 hours.
Sorry for my poor english. good news : Every things is OK now. It seems i have some problems with the IDE controler VT82C586B when DMA is enabled (which is the default. Even with CONFIG_IDEDMA_NEW_DRIVE_LISTING.) and i use xawtv (card : Bt848) in same time. As recommended by some README in bttv, i have changed the latency of the card but that don't fixe my freeze problems. I also tested with the lastest stable release of bttv (0.7.100) without success. The linux-RH-2.4.17 has this problem also, but it appeard seldom. I encountered this problem with all my hard disks. I don't do any test with cdrom. For me this is a very high problem. I experiment two massive filesystem corruption (with ext3 and error behavior set to remount-ro). I try to test linux-2.5.47. The bttv modules can't be build. I grab the version 0.9.1 from the bttv site and build modules out of the linux tree. But when i try to read files from disks connected to the IDE controler VT82C586B (with or without DMA enabled) i get after less than 2 seconds : kernel BUG at drivers/block/ll_rw_blk.c:1910! kernel: invalid operand: 0000 kernel: bttv video-buf i2c-algo-bit i2c-core videodev v4l2-common soundcore dummy0 af_packet ide-cd cdrom rtc unix kernel: CPU: 0 kernel: EIP: 0060:[<c01a63d7>] Not tainted kernel: EFLAGS: 00010246 kernel: eax: 00000000 ebx: 00000000 ecx: 00000000 edx: cf606f00 kernel: esi: cf606f00 edi: 00000001 ebp: 00000001 esp: ca26fc0c kernel: ds: 0068 es: 0068 ss: 0068 kernel: Process mv (pid: 752, threadinfo=ca26e000 task=ca86b340) kernel: Stack: c12b8e00 cf606f00 c015a9de 00000000 cf606f00 00001000 c015abea 00000000 kernel: cf606f00 00001000 00000000 cff5aa80 c1377340 000001cc 00000001 0000000c kernel: ca2190bc 00000010 00000000 00000000 cfc81d40 000a82cf cff5aa80 cfaca300 kernel: Call Trace: [<c015a9de>] [<c015abea>] [<c01402df>] [<c015ae6f>] [<c016dba0>] [<c0132eff>] [<c0138769>] [<c016dba0>] [<c0133212>] [<c013881f>] [<c01388e4>] [<c012b8d0>] [<c012bbf0>] [<c012be8a>] [<c012bbf0>] [<c012bf2a>] [<c013eb4c>] [<c013ec5a>] [<c013eefe>] [<c01090a3>] kernel: Code: 0f 0b 76 07 6c 16 23 c0 eb aa 90 8d b4 26 00 00 00 00 8d bc The files are readed from a raid 0 software partition. Note that linux-2.5.47 (like 2.4.x) also enable DMA by default for the IDE controler VT82C586B. I don't have any problems with the IDE controler HPT370 with DMA enabled (which is not the default for this controler) and i can play safety with hdparm with this controler. I use alsa and alsa version 0.9.0rc5 can freeze my system sometimes (strangly there is no problem with linux 2.4.17). An update to version 0.9.0rc6 fixe this problem. I have said earlier that linux-2.4.20-rc1-ac1 spend two more cpu usage when i play avi file with mplayer. It is wrong. Perhaps i forget to compile mtrr support. With kernel-RH-2.4.18-18 i still have some problems with keyboard under X. Currently i use kernel-RH-2.4.19-0.pp.15 (this kernel don't suffer of the keyboard problem). conclusion : Don't enable DMA with the IDE controler VT82C586B when bttv is used. alsa version 0.9.0rc5 can freeze the system. version 0.9.0rc6 is fine. kernel-RH-2.4.18-18.8.0 still have some problem with keyboard under X.
I update my bios and the problem is solved (bios v3.3 to v3.7). I can now enable DMA with the IDE controler VT82C586B and use bttv at the same time without freezing my computer. Product specification : http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=29&MODEL=MS-6380 Bios upgrade : http://www.msi.com.tw/program/support/bios/bos/spt_bos_detail.php?UID=28&NAME=MS-6380%20Ver2.0 I always have some trouble with keyboard under X11. Can someone close this bug?
I am really sorry. I always have this problem. After bios update my uptime was 15 days and with intensive stress of disks with DMA enabled. Lastly i rebooted my system and now my system freeze quickly (around 3 min) when i use disks pluged into the IDE controler VT82C586B with DMA enables. This make me crazy.
I slow down the transfert mode of Maxtor 90340D2 disks : hdparm -X mdma0 The defaut setting is mdma2. No freeze since 3/4 weeks.
