When trying my PCMCIA HD under FreeBSD 4.1R I noticed the following: 1) there was a VERY long time gap between when the drive was recognized on insertion, and when the drive was powered up and mountable (see timeline below) 2) I can power down (pccardc power 1 0) this drive without unmounting. unmounting afterwards causes panic fatal trap 12 (supervisor read, page not found) Number 1 is an inconvenience, and it would be nice to alter some settings somewhere to speed up the process since the machine seems to be locked up during the interval. Number 2, however, has me a little worried. This suggests that pccardc/d do not interact with the file system. That would imply that any uncommitted writes would not be flushed to the drive before the drive is powered down. [Please excuse my ignorance if Unix does not have the concept of delayed writes.] Thanks for you thoughts, Greg Smith ---timeline--- 9:44:38 [card physically inserted] 9:44:41 card inserted, slot 1 9:44:47 card ---- recognized 9:47:01 ata2 at port ---- 9:47:11 ata2-slave: ata_command: timeout waiting for intr 9:47:11 ata2-slave: identify failed [power up of drive] 9:47:15 ad4 248MB ---- at ata2-master using BIOSPIO 9:47:15 ata2: ---- inserted when repeating the above right afterwards the 0:02:14 delay was slightly changed to 0:02:12, so this was not a fluke. ---win95 timelines--- 9:55:00 [card physically inserted] 9:55:03 machine beeps 9:55:06 card powered up 9:55:12 card mounted automatically (contents shown) 9:55:30 [card power down requested] 9:55:33 card powered down 9:55:33 card unmounted automatically (contents disappear) the last two are probably simultaneous, except for the delay in redrawing the screen ---config--- device ata device atadisk ---pccard.conf--- io 0x110-0x160 0x180-0x1e0 0x230-0x2e0 0x300-0x320 0x340-0x360 irq 9 11 memory 0xd4000 96k # Integral Peripherals Viper HDD Series card "INTEGRAL PERIPHERALS" "ATA CARD" # config default "ata" ? config 0x01 "ata" ? iosize 16 logstr "Integral Peripherals ATA HD" ---fstab--- # Device Mountpoint FStype Options Dump Pass# /dev/ad0s2b none swap sw 0 0 /dev/ad0s2a / ufs rw 1 1 /dev/ad0s2f /usr ufs rw 2 2 /dev/ad0s2e /var ufs rw 2 2 proc /proc procfs rw 0 0 /dev/ad0s1 /c msdos rw 0 0 /dev/fd0 /a msdos rw,noauto 0 0 /dev/fd0 /b ufs rw,noauto 0 0 /dev/ad4s1 /d msdos rw,noauto 0 0 ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
