Now the kernel does not panic, but "mount" does not return.
That's the on-screen log with "boot_verbose=yes":
$ mount /cdrom
acd0: TIMEOUT - READ_BIG retrying (2 retries left)
acd0: unknown transfer phase
ata0: reiniting channel ..
ata0: reset tp1 mask=03 ostat0=d0 ostat1=d0
ad0: stat=0x50 err=0x01 lsb=0x00 msb=0x00
acd0: stat=0x00 err=0x01 lsb=0x14 msb=0xeb
ata0: reset tp2 stat0=50 stat1=00 devices=0x9<ATAPI_SLAVE,ATA_MASTER>
ata0: resetting done ..
ata0: reiniting channel ..
acd0: FAILURE - ATAPI_IDENTIFY timed out
acd0: timeout sending command=a1
acd0: error issueing ATAPI_IDENTIFY command
ad0: timeout sending command=ec
ad0: error issueing ATA_IDENTIFY command
ad0: timeout sending command=ec
ad0: error issueing ATA_IDENTIFY command
ad0: WARNING - removed from configuration
after the "ad0: WARNING - removed from configuration" message, I do not get
the shell prompt.
However, pressing ^C seems to unblock "mount", but then I cannot eject the cd
(combo seems locked).
Successive mounts blocks indefinitely.
PS: I recompiled only the kernel with sources downloaded yesterday night
(CEST), and I think I do not need to recompile also the "world" (it tooks 4
hours...), correct? let me know otherwise.
