| |
Alan and All,
I've detected a bug somewhere in 2.4.0-acX, at least in ac4, the first ac kernel I built. It seems that I can't mount a scsi zip disk in, unless the following has occurred:
1. There is a disk in the zip drive when I boot.
2. I fdisk the scsi block device and re-write the partition table. (I accidently discovered this).
in other words I get this: mount: /dev/sda4 is not a valid block device. If I try to insert a zipdisk and mount it after I boot up.
This problem does NOT occur as late as 2.4.0-final.
Specifics of my system:
The SCSI board is a real cheap SYM810A based Fast SCSI-2 PCI board.
I use the sym53c8xx driver built in, as is scsi disk support. The only thing I use the scsi board for is the external zip 100 drive.
It still occurs in ac6. (I've only build ac4 and 6).
Here is the specifics from a dmesg of 2.4.0 booting: (2.4.0-ac4 and 6) is the same. SCSI subsystem driver Revision: 1.00 sym53c8xx: at PCI bus 0, device 13, function 0 sym53c8xx: setting PCI_COMMAND_PARITY...(fix-up) sym53c8xx: 53c810a detected sym53c810a-0: rev 0x12 on pci bus 0 device 13 function 0 irq 10 sym53c810a-0: ID 7, Fast-10, Parity Checking sym53c810a-0: restart (scsi reset). scsi0 : sym53c8xx - version 1.6b Vendor: IOMEGA Model: ZIP 100 Rev: C.22 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi removable disk sda at scsi0, channel 0, id 5, lun 0 sym53c810a-0-<5,*>: target did not report SYNC. sym53c810a-0-<5,*>: target did not report SYNC. sym53c810a-0-<5,*>: target did not report SYNC. sym53c810a-0-<5,*>: target did not report SYNC. sym53c810a-0-<5,*>: target did not report SYNC. sda : READ CAPACITY failed. sda : status = 1, message = 00, host = 0, driver = 28 sda : extended sense code = 2 sda : block size assumed to be 512 bytes, disk size 1GB. sda: I/O error: dev 08:00, sector 0 unable to read partition table
